Recently, I’ve been reading a lot of articles that are trying to temper the expectations related to autonomous vehicles, and with great satisfaction, I would like to say…it’s about time. If you bothered to read my article about VR being overhyped and underdelivered, you probably noticed I mentioned some other technologies that fall into that same category, and autonomous vehicles are one of them. It’s not that I’m skeptical about the benefits of the technology, I just understand that achieving those benefits are significantly further down the road than anyone wants to admit. If you don’t believe me, keep reading…
According to IHS Automotive, a leader in automobile industry statistics, at the beginning of 2016, “the average age of all light vehicles on the road in the U.S. had climbed slightly to 11.5 years.” Even if fully autonomous cars were available today, America wouldn’t see any significant market penetration for at least a decade, and most of it would be limited to higher socioeconomic areas. To everyone who thought self-driving cars were going to be bobbing and weaving down the streets of their local cities by 2020, you should probably prepare to be disappointed.
You may be asking yourself, why is the timeline is so important? It’s important because of one of the most significant benefit promised through the evolution of autonomous vehicles is related to safety, and achieving it can’t be accomplished until autonomous vehicles comprise ~90% of all cars on the road. Keep in mind that number is my personal calculation, but until self-driving cars make-up a significant portion of vehicles on the road, cities won’t see any significant decrease in the number of automotive accidents that occur every year.
Do you know the most common cause of accidents for self-driving vehicles? It’s human error, the same thing it’s always been. Accidents have been happening for the same reason for as long as I can remember. Someone makes a wrong decision, puts other people’s lives at risk, and placing a computer at the helm of one of the vehicles won’t change this fact as long as there are humans on the road with them. Waymo, autonomous vehicle spinoff from Google, stopped reporting their accidents at the beginning of 2018, making it harder for interested parties to keep up with their efforts to remove human error from the roadways, but the good news is, California has archived all of the previous reports on their site if you’re interested in reading through them.
The most common accident type reported were humans rear-ending self-driving cars. Because computers don’t make decisions, they make calculations; autonomous vehicles will ALWAYS run the risk of being plowed into at a yellow light when there are humans in the cars surrounding them. If a computer controlled vehicle can safely stop before the intersection, it will do so, while its human counterparts can be expected to merely say the light was “pink” when they hit the intersection. Human behavior of this type is precisely why autonomous vehicles face such an uphill battle when it comes to public acceptance.
Humans expect the vehicles around them to make decisions in the manner they do, and that means running into the back of a lot of computer-driven vehicles. Running a yellow light is one of the riskiest human driving behaviors on the road, one that we take for granted as we’re driving with other humans, but it’s also one that computers won’t tolerate. Other behaviors, like coming to a complete stop at a stop sign (never happens in California…) and when turning right on a red light, will all lead to accidents between the computer and human-driven vehicles.
Winner Take All
Computers will always strive to provide an element of society that humans can never achieve, perfection, and their achievement of it will only further highlight human imperfections (more accidents). Ultimately, it will be a human that forces a self-driving car to have to choose between saving the lives of its passengers or taking the lives of other drivers. Right now, some engineer is sitting in a room evaluating a Kobayashi Maru scenario that forces a self-driving car to choose lesser of two evils in an unwinnable situation.
For example, a human driver falls asleep and crosses over into oncoming traffic, and someone has to die. Will your self-driving car decide to save its passengers or the passengers in another vehicle? You won’t know the answer to the question until it’s too late. Simply knowing that an engineer has to program a predetermined outcome into a computer for this scenario is already a scary enough thought. What I’m more afraid of is the method that needs to be employed to significantly decrease the chances of any unnecessary carnage happening as a result of these kinds of scenarios.
In a situation where a catastrophic event is inevitable, and death is an assured outcome, the best way to minimize the damage is to make sure all autonomous vehicles react to the situation in the same way. I’ll give you a second to digest that…
“To prevent additional cars from being involved in accidents, all autonomous vehicles on the road should be running the same system so they can anticipate the calculations of other vehicles in their proximity. Think of it as hive mind.”
If a car suddenly blows a tire on the freeway, every autonomous vehicle should avoid the car, in unison, at the same speed, in the same direction, to prevent any unnecessary collisions. If all the cars are running the same system, the other self-driving vehicles on the road won’t need to guess the calculations of the other vehicles involved; they’ll already know what’s going to happen. Instead of having a ten car pile up, the result is a two-car accident, saving more lives in the process.
This aspect of the technology isn’t frequently discussed, but we all know what it means, someone needs to have a monopoly on self-driving vehicle technology. Even though the United States has antitrust laws in place, to truly reach the pinnacle of efficiently concerning autonomous vehicles, only one technology should be implemented. So I’m putting everyone on notice…the self-driving car market is playing a winner take all game, and they should all know that winning is everything.
