The Economic Consequences of Self-Driving Trucks

An anonymous reader writes: Last week we learned that self-driving big-rig trucks were finally being deployed on public roads in Nevada for testing purposes. Experts consider trucking to be ripe for replacement with AI because of the sheer volume of trucks on the road, and the relative simplicity of their routes. But the eventual replacement of truck drivers with autonomous driving systems will have a huge impact on the U.S. economy: there are 3.5 million professional truck drivers, and millions more are employed to support and coordinate them. Yet more people rely on truckers to stay in business — gas stations, motels, and restaurants along trucking routes, to name a few.

Now, that's not to say moving forward with autonomous driving is a bad idea — in 2012, roughly 4,000 people died in accidents with large trucks, and almost all of the accidents were caused by driver error. Saving most of those lives (and countless injuries) is important. But we need to start thinking about how to handle the 10 million people looking for work when the (human) trucking industry falls off a cliff. It's likely we'll see another wave of ghost towns spread across the poor parts of the country, as happened when the interstate highway system changed how long-range transportation worked in the U.S.

My brother is a truck driver, and from what he has told me, and also what I have seen reported multiple times, and what I have seen myself, the vast majority of accidents involving trucks are caused by car drivers misbehaving around truck. They pull stunts like pulling in front of them at merges then hitting the brakes. An autonomous truck will hit such a car just like a manned truck, so I think the claim that automating the trucks will save most of those lives is wrong.

      Your brother is correct. Professional drivers can drive hundreds of thousands of miles per year, while Joe Blow in his Honda may do 15,000. Statistics show that most accidents involving a larger truck are, in fact, the fault of the car. So automating trucking won't help.

      To give a counterexample, I was driving down a long hill that I have driven daily for 20+ years. At the bottom of the hill, right before it went around a curve, I saw cars hitting their brakes, and knew there was probably a traffic jam around the corner, so I started slowing down.

      There was a truck driver pretty far behind me, and he didn't bother slowing down until he came around the curve, saw the traffic jam, locked his brakes, and ran off the road, and blamed me for the accident.

      I'm a physics major, so I measured the location of where he locked his brakes, and the point he came to a stop. A little high school algebra showed he was moving 80-85 MPH in a 70 MPH zone when he hit his brakes.

      For that reason, I subsequently installed a dashcam in my car. It pays for itself the first time some idiot lies and tries to pin the blame on you.

      What makes you think that the autonomous truck will hit the car just like a manned truck? I'd think that with the sensors on the truck tied directly into the autonomous control systems the autotruck could react thousands of times faster and more effectively than a human being truck driver.

      Hmm... looks like somebody failed at learning Amdahl's Law.

      Let's say a truck is driving at 60 MPH (88 feet per second) when somebody jumps in front of it, 88 feet away. The driver will take 0.5 seconds (44 feet) to react, then the truck's air-brakes will take another 0.5 seconds (44 feet) to engage. By that time, the truck will have hit the person. Then the truck will take another 355 feet to come to a stop.

      Let's replace the human-driven truck with an automated one, and assume that the computer is unrealistically perfect and manages to reduce the reaction time to zero (seconds or feet). In that case, it still takes 0.5 seconds (44 feet) for the air brakes to engage, so the truck has "only" 311 feet of braking distance left to travel when it hits the person.

      In other words, reaction time accounts for only about 10% of the total stopping distance, so the maximum improvement gained by switching to an autonomous truck would be about 10%. That's not zero, but it's also not "thousands of times" better, as you claimed.

      That won't help. The problem with trucks isn't human reaction speed, it's the sheer amount of kinetic energy that needs to be dissipated for one to stop. A 60-ton truck going at 50 mph has 29 MJ of kinetic energy. For it to stop, every single joule needs to go somewhere, and with current technology that means they'll turn to heat. And that means it's going to take a while as that heat dissipates - the brakes will literally melt if you try to brute-force a shorter braking distance, for example by increasing braking system pressure.

      Alternatively, just consider how much damage is caused by a truck crash. Physics don't care if it's another car's rear or the truck's own brakes it's pushing against; any object that tries to stop its motion in a hurry is going to be hit by those same forces.

      If there's that much difference in stopping distance then the truck is criminally poorly maintained.

      No, the fact a truck going the same speed as a car can take three times the distance to stop is physics. See this chart.. The car weighs around 3000 lbs, and the truck is 40,000-80,000 lbs. The car has a lot more rubber per pound on the road so stops faster. And no matter which driver caused it, when a 40 ton truck hits a 1 to 2 ton car, the car loses. It is the same problem with many motorcycles being able to stop faster than a car.

    There are a lot of trucks where liability or small tasks that still require human judgment will keep with human drivers for a good long while yet. Fuel Trucks delivering to local gas stations, septic trucks and heating oil trucks that have to find a port in every person's yard, etc...

    I do wonder whether the amount of stuff that falls off the back of the truck will go up or down. Less oversight of the stuff, but less chance for a driver to be in collusion with the people who fall things off the back of trucks.

    Honestly, we can kick that can a lot farther down the road than you may suspect. When self driving trucks first become a reality, they are going to be used as 'autopilot' where they do the over-the-highway driving, and human drivers do the 'last mile' because the last mile can be a tricky bastard for a human, let alone a computer. Many deliveries take place where the truck must jack knife the truck in the middle of a street, back into an ally and around a corner in reverse, and center up on a loading dock, or some variant thereof. As the initial action (blocking all lanes of traffic) requires something that by most standards would be a traffic violation, it becomes extremely hard to program a computer to make the final approach to the dock, while still following all its 'road safety' rules. It could be decades before we get our software/AI advanced enough for that, and until then, self driving trucks are going to require skilled drivers in the seat, waiting their turn.

    I wouldn't say it's worse than useless. But it may not be the panacea that we expect.

    First, I have my doubts about the whole "A.I. Can Handle Anything" theory. Weather, accidents, and construction can create very creative roadways where you will want a driver behind the wheel who'll be able to figure out and work with human beings on the scene (for example, a cop doing traffic control around an accident).

    So you'll still want drivers. The question is, how many drivers will you need?

    Consider long-haul trucks, which are the ones that are really ripe for automation. They usually have two drivers so that they can run 24 hours at a stretch. I believe--and I may be off--that the rules for these people require that they drive no more than 12 hours. It might be 10 hours, I don't remember. But in any event, the reason you have two drivers is so that you don't have a truck spending 12-14 hours sitting by the side of the road while the single driver sleeps.

    You could get rid of one driver right there. A long haul truck with one driver who can sleep for 12 hours and will only be woken up if something weird is going on that the truck can't handle so it pulled off to the side of the road. That's still saving money versus having two drivers and is certainly not "worse than useless."
