Do you even drive, bro?

This is a personal rant, not a serious essay.

I drive a 2020 Chevy Bolt electric vehicle. All battery. I have used it like a mini pickup truck with a piece of plywood laid over the folded down back seat and banged around the dirt roads of Vermont for the past six years. I have to say that it is the best car I have ever owned. With the weight of the battery pack at floor level it handles beautifully. The acceleration is smooth and quick. It is quiet and vibration free. Aside from the two times I have bottomed it out in the mud it hasn’t required any major repairs (and they were under warranty). I’d buy another.

But still, I have to ask, have any of the designers of the car’s interior ever driven during daylight hours? Have they ever tried to operate a car’s climate controls while in motion? In winter? For that matter, did the designers of the charge port understand the concept of snow?

Some bonehead decided to put a strip of chrome plastic trim across the top center of the dashboard above the touchscreen. It is curved in both the left/right and up/down directions. This means that when the sun is overhead the driver cannot escape a point of blinding solar reflection from the center of the dashboard. That’s an actual safety hazard. I had to get some gray tape and cover it.

Likewise, there is a reflective chrome Chevy bowtie symbol in the center of the steering wheel. When the sun comes in from the upper left or over the driver’s left shoulder that is similarly blinding.

Location aside, why is there any reflective surface on the dashboard anywhere in any orientation? It’s an annoyance and a safety hazard. Anyone driving the car for an hour on a sunny day would notice this. How did this get through the design process? I am at a loss.

The climate controls include a dial for temperature control with a digital display in the middle, a few virtual touchscreen buttons, and a cluster of physical buttons. The virtual buttons can’t be operated with gloves on. I live in Vermont. Several months of the year I have to cover my hands when outside. The virtual buttons also have no tactile response or physical definition, so the driver has to look at them to touch them and to see if they have been activated. The physical buttons also need visual confirmation. The fan up/down buttons need to be located and pushed repeatedly while the driver looks at a tiny bar graph display on the screen. It’s all annoying and a hazard.

And that temperature dial. Why? The display tells me the temperature of a sensor somewhere in the car where my body is not. I have to look at it to see what I have done. And what I have done is pointless. I don’t care if that sensor is detecting 71F or 72F. There are so many variables. What am I wearing? What’s the temperature outside, and have I been out in it? I don’t need 71F or 72F. Depending on the season and my condition I need

Meat locker cold

Kind of cold

Cool

Neutral – whatever it is outside

Warm

Hot

Bread oven

These are all subjective, not numerical values.

Here’s what I want: Three vertical, physical sliders, side by side, in the middle of the dash.

The left hand one is the fan setting, zero at the bottom and 100% at the top.

The middle one is temperature. Meat locker at the bottom, a detent for neutral in the middle, and bread oven at the top.

The right hand one controls where the air goes. Windshield defrost only at the top, feet only at the bottom, and a logical progression of combinations in between, with detents. The middle detent is every vent at once. If they want, it could be a vertical array of physical buttons with a definitive click feel.

They could put a switch at the passenger end of that with direct vent up and recirculation down.

All of these could be operated by feel with gloves on. It really wouldn’t be any more expensive than the instrument clusterfuck they have now.

And then there’s the charge port, or snow funnel. It’s a forward opening door with a push to open, push to close latch. After use in a few precipitation/freeze/thaw cycles it is a punch three times to open, slam twice to close latch. There’s a recess behind the door with the charger receptacle in the middle. It is angled up. Snow accumulates around the receptacle in the pocket space, then melts, and refreezes. It fills the rubber V gasket around the edge and freezes. It gets into the latch mechanism and freezes. It even gets into the plug/receptacle junction and freezes so the charging plug has to be wiggled carefully until the ice breaks free. I have spent a lot of time carefully picking ice and snow out of the charge port. I am sure that every driver north of 35 degrees latitude has done the same.

Could the charge port door open upwards? Like a sort of umbrella? Put something in that deploys above the charge port to keep out the snow. This should not be a revelation to the designers. It’s basic user experience in the snow belt.

As long as I’m ranting about snow and user experience, the aerodynamics of the hatchback are such that the rear license plate is completely obscured after fifteen minutes of driving in the snow and the backup camera is unusable. For that matter, the backup camera becomes unusable due to accumulated dirt quite often. Aerodynamics is a big deal with you guys, unless you want something to look extra cool. Oh well.

As I said, overall, I would buy one again. But really, it’s so frustrating to drive something that got the hard stuff right and face planted on the easy stuff.

Rant over.

You Are On Car Welfare; The Everyday Insanity of Driving 

I always think about the absurdity of driving at least once when I’m driving. The system has evolved so slowly over time that we find ourselves in normalized insanity.

When I want to go somewhere I strap myself into a steel box on wheels that weighs about a ton and a half. I strap myself in because it is dangerous out there. Over 35,000 people are killed every year doing this, and for each death about 8 people are seriously injured. Some are crippled for life. The death toll is the equivalent of two fully loaded passenger jets plummeting out of the sky every week. If that were happening the problem would solve itself because nobody would fly. We each have about a 1 in 107 chance of ending our lives in a car accident. We each have a lifetime chance of about 7.5% of being hospitalized after a crash. But we drive. It’s about the freedom of the road, right?

Well, freedom of departure time, perhaps. If you are driving on a two lane road and you drift a couple of feet to the left you will probably smash head on into another vehicle at a combined speed approaching 100 miles per hour. A few feet to the right and you’ll hit a tree, a power pole, a pedestrian, or a building. You have to thread the needle at high speed, surrounded by others trying to do the same. Or, perhaps, not trying quite so hard to do the same. We have all seen drivers engaged in extraneous activities, from placating children in the back seat to talking on the phone. (Phone use causes equivalent impairment to a BAC of 0.14%, or six drinks in one hour) (and no, a hands-free earpiece makes no difference*) Road deaths were declining slightly until the widespread adoption of the mobile phone. Now distraction is starting make inroads on alcohol as a source of highway deaths.

An expression for an exceptionally short time is “the blink of an eye.” Medical science says that this is about a third of a second. At 65 miles per hour that is just over thirty feet of travel. Look down at your dashboard for a full second and you have traveled 95 feet. If you have had even a few drinks and get headlights in your eyes you can be blind for three seconds or more, which is almost the length of a football field.

Those of you who have read my blog before know that I am an energy wonk. Driving is insane on this front as well. A reasonably well tuned car might be 15-20% efficient at converting gasoline into forward motion. Your car is really a rather efficient furnace that happens to roll around with its spare energy. Your car outweighs you about 20:1. Best case scenario, one gallon of gasoline out of 100 actually pushes you, personally, down the road. This is, in theory, the point of the exercise. The other 99% is either wasted as heat or used to push the vehicle itself around.

And push it does. Most of the energy your car does turn into motion is used to push air out of the way. Air drag goes up by the square of the speed. Accelerate from 20 mph to 40 mph and the force needed to keep your car moving goes up four times. Sadly, the average car of 2021 is no more aerodynamic than the average car of 1935. We know how to do much better. The General Motors EV-1 electric car had a drag coefficient (Cd) of 0.19, compared to an average car with 0.3 to 0.4. For comparison, the Cd of a ball is about 0.47. Someone estimated that if the EV-1 had an ordinary four cylinder engine it would get 75 miles per gallon. But no, we want cars that look like slightly rounded bricks.

In total, about 10% of the world’s oil supply ends up in our gas tanks. Put 10% of the deaths in oil-state wars on our account, plus 10% of the oil-based pollution and greenhouse gases.

We drive a lot. People in some major-metro suburbs drive upwards of two hours to get to work, alone in their giant brick-shaped vehicles like everyone else. An average car today travels over 14,000 miles per year. Back in the 70s the number was 7,000 miles. Just for perspective, look up your daily commute on a mapping/navigation app. The standard Google Maps has little icons across the top for cars, bikes, public transit, and walking. Hit the walking icon. For some people their daily commute would take days on foot. A hundred years ago most people were walking to work. Cities and towns were set up that way. Now, because of single use residential zoning, in many suburbs it is illegal to site businesses within walking distance of people’s homes.

It turns out that we don’t get a lot for what we put in to our cars. A writer named Ivan Illich, in his book “Energy and Equity” estimated that an average car owner spent 1600 hours per year either driving, earning money to buy, fuel, and maintain the car, or otherwise engaged in car related activities. At 7,500 miles per year that worked out to 4.6 miles per hour; a brisk walk. I did a basic calculation using the U.S. Department of Transportation estimate of an average 14,263 miles per year for 2019. On average we spend 563 hours in our cars each year and spend $9,561 on the costs of ownership. At a median wage of $19.33 per hour a median American works 494 hours to earn that. This doesn’t include the time we spend in repair shop waiting rooms, at gas stations, or at the DMV. As it is, this works out to 13.5 miles per hour, a reasonable biking speed.

The actual number is undoubtedly lower. There’s also the $100 billion annual cost of vehicle air pollution, including 53,000 deaths, and $242 billion in economic losses from crashes. We have a personal transportation system with a death toll that rivals the opioid epidemic and an ROI on our time and money that can’t beat a bicycle rickshaw.

Most of the money we spend on driving is hidden. Put bluntly, we are all on car welfare. A study by the Vermont state government found that a pay-as-you-go gas tax would double the price of fuel. That is, if we paid the full cost of road building and repair, law enforcement, and other driving-related government expenses in a gasoline tax it would add $3.25 to the price of a gallon. That gallon of gas is subsidized anyway. If we paid all the associated costs of gasoline (oil company subsidies, pollution related illness, our military guarding oil shipping lanes, etc.) then gasoline would cost at least $10 per gallon. At an unsubsidized $16 per gallon, how much would we drive?

We don’t distribute the costs evenly either. It’s one of those startling engineering truths, but damage to roads by vehicles goes up by the fourth power of the vehicle weight per axle. A Fiat 500 has a curb weight of around 2500 pounds. A Ford F150 crew cab pickup has a curb weight about twice that. Per mile traveled, the Ford pickup will cause 24 or 16 times the damage to the roads. A U.S. General Accounting Office study found that a fully loaded semi (5 axles, double tires) causes 9600 times the damage of a passenger car. Of course, neither the F150 nor the semi pays anything close to that kind of premium for damaging the roads. Car welfare is a fraction of truck welfare.

The problem is that we are trapped. Our entire lives are twined around the automobile. That technology defines our lifestyles, our daily schedules, urban design and our city, state, and federal budgets. It has squeezed out alternatives in our budgets and our landscape. Most importantly, it has squeezed the alternatives out of the general public imagination. For most Americans, owning and driving a car seems an inexorable, unquestioned part of life. It’s just how you get places. And you have to get places because they aren’t close. Traffic is like the weather; something to be endured but not changed.

Your choice of car is an expression of your identity as much as a mode of transportation. This is true whether you thought about it that way or not. Cars are inescapable in film and television, as background, as enabling technology, as drivers of plot, and as symbols. The idea of an American future without cars is relegated to dystopian, post-apocalyptic science fiction.

Many years ago, when I was converting cars to electric power, one of my business partners said, “Converting cars is easy but converting people is hard.” The primary problem of transforming our transportation system is changing minds. Most people don’t think there is a problem. Most that do realize there’s a problem think that the solution involves a modification of cars; new fuel, self-driving, tweaks.

There’s another saying: The problem will eventually solve itself, but not in a nice way. The automobile era is just that; an era. Geology and physics will not let this go on forever. In the U.S. we have a quarter billion two-ton steel boxes on wheels, each driving 14,000 miles a year, traveling 65 miles per hour, with one person per car, over huge flat strips of petroleum and gravel. There is no way to reform that into sustainability. The inevitable decline in the quantity and quality of fossil fuels will end the car era. The only question is whether we anticipate this and change our ways before the crisis hits.

So, what do we do? First, get the big money out of politics. This is my “Carthago delenda est.” Until those who profit from wasted energy and lives can no longer choose our lawmakers we will get no change.

If we can win that battle, we need to take a step back and look at basic principles. We tend to mistake mobility for access. We want to get to work, to get food, to see each other, to play. Right now that means going some distance, so we think about speed and comfort and route capacity. However, what we really want is to end up in close proximity to these things. Changing zoning and urban design could bring these things closer.

Some people and places are, by necessity, farther than a walk or bike ride away. Climate and terrain may be a problem. In that case, we should consider the number of people on any given route, the necessary level of comfort for the distance, the appropriate speed for the distance and environment, terrain, local climate, and the built environment. The point being, start with a clean sheet of paper and try to use the least amount of materials and energy per passenger mile to get the job done safely. The result won’t look like a car on a road.

That last sentence circles us back around to job #2, right after campaign finance reform: persuasion. As I said before, the ubiquity of cars combined with massive hidden subsidies has squeezed alternatives out of our collective imagination. The costs and consequences of the car have been compartmentalized away from our driving experience. The beginning of change is the awareness of the flaws in life as it is. The facts and numbers I have laid out for you here have to become part of the general public consciousness before people will be willing to change. Even then, there will be an excruciating process of unwinding our emotional attachment to the present system. Every fact has an emotion attached. The people and corporations that benefit from our subsidized carnage will weaponize these emotions. It will be a generational battle.

To reiterate: Geology and physics will end the automotive era even if we don’t. Our only decision is whether we pull over and park or drive off a cliff.

 

*I know what you’re thinking. Bullshit. No. Drunks think they are driving just fine. The science is done. You are not magically different from everyone else in this regard. If you think someone who downs six shots and drives is immoral then ignore your phone while you drive.

Chill to Fight Climate Change

There’s something you can do today to fight climate change. It’s effective, it’s easy, it costs nothing, it doesn’t require a lifestyle change, and most of you are going to hate it. You are also going to hate me for bringing it up because there is no rational reason not to do it. It is literally a crime not to. Literally.

 Stop speeding. Drive the speed limit. That’s it.

 Here’s the math. (If you don’t like explanations, speeding in the U.S. is responsible for at least 4.2% of our oil use, 1% of world oil use and 15,000 deaths annually)

 At highway speeds, most of your energy goes to pushing air out of the way.  Air drag increases by the square of your speed. Double the speed means four times the drag.  A small increase in speed ends up making a lot of difference in energy use.

 Compared to driving at 65 miles per hour, driving 75 mph will cost you 15% of your gas mileage and driving 80 mph will cost you 20%.

It’s hard to get an exact number on what percentage of drivers speed, and by how much. Study results vary. Generally speaking, about 75% of drivers speed, and about 80% of drivers surveyed think that driving ten to twenty miles per hour over the speed limit is fine. Absolute speed limit compliance is low. Biased self-reporting undoubtedly minimizes the problem.  It would be safe to say that 75% of drivers are losing about 15% of their mileage by speeding.

Road transportation accounts for 40% of our oil demand. Multiply it all out and about 4.5% of U.S. oil use is just due to speeding. The U.S. accounts for 20% of world oil demand, so speeding Americans increase world oil demand by about 1%.

Just an aggressive driving style, minus speeding, can cost drivers another 25%, so slowing down *and* calming down behind the wheel could cut world oil consumption by 2%.

We’d still have the other 98% of oil-based emissions to deal with, but it is free, it is easy, and it’s the law. When I say it’s the least we can do, I mean it’s the very least we can do.

If contributing to the survival of the planet isn’t enough to motivate you, consider the more direct deaths. According to the National Highway Traffic Safety Administration, speeding was a contributing factor in 9,478 deaths in 2019. An MIT study found that air pollution from vehicles causes 53,000 deaths annually. The inefficiency of speeding causes about 10.5% of those, or 5,565. If everybody slowed down, 15,000 Americans would not have to die prematurely. One of them could be you, or someone you love.

Cruise control is your friend, and a friend to nature. Set it at the speed limit. Cease worrying about speed traps. It’s really, really the very least you can do.
