Last week, the National Highway Traffic Safety Commission (NHTSC) formally proposed to mandate that all new cars be equipped with “vehicle‐​to‐​vehicle” (V2V) communications, also known as connected‐​vehicle technology. This would allow vehicles stuck in traffic to let other vehicles know to take alternate routes. It would also allow the governments—or hackers—to take control of your car anytime they want.


The good news is that the Trump Administration will take office before NHTSC has a chance to put this rule into effect, and may be willing to kill it. The bad news is that this rule will feed the paranoia some people have over self‐​driving cars.


This article, for example, considers self‐​driving cars to be a part of the “war on the automobile” because they offer an “easy way to track the movements of individuals in society.” In fact, the writer of the article is confusing self‐​driving cars with connected vehicles. As I’ve previously noted, none of the at least 20 companies working on self‐​driving cars or software appear to be making V2V an integral part of their systems. This is mainly because they don’t trust the government to install or maintain the infrastructure needed to make it work but also because self‐​driving cars don’t need that technology.


There are good reasons to be paranoid about connected‐​vehicle mandates. First, they will give government the ability to control your car, and some governments in the United States have shown that they are willing to use that control to reduce your mobility. The state of Washington, for example, has mandated a 50 percent reduction in per capita driving by 2050. This is a state that has forbidden people to build homes on their own land if they live outside of an urban‐​growth boundary. If they can’t reduce per capita driving through moral suasion, it is not too much of a stretch to imagine that they will just turn peoples’ cars off after they have driven so many miles each month.


Second, if every car uses exactly the same vehicle‐​to‐​vehicle software, they will be incredibly vulnerable to hackers. Remember that hackers figured out how to remotely control a Jeep that Chrysler had wired to the cell phone network. Chrysler responded by recalling 1.4 million cars to install a firewall between the network and the car’s operating system. But now the government wants to mandate that all cars connect their operating systems to the cell phone or other wireless network, with no firewalls allowed.


While the risks of mandatory V2V systems are significant, the benefits are tiny. Marc Scribner of the Competitive Enterprise Institute notes that, “As NHTSA readily admits, hypothetical safety benefits of the mandate will be trivial for the next 15 years, at which point far superior automated vehicle technology may be deployed to consumers,” especially if manufacturers aren’t locked into technologies prescribed by the government.


People should not be paranoid about self‐​driving cars because none of the technologies required for self‐​driving cars would allow someone to remotely control your car. But people should be paranoid about V2V communications, especially those mandated by the government. Some auto makers are already offering various connected technologies with their cars, such as OnStar, which leaves it up to consumers whether they want to buy those kinds of systems and gives manufacturers incentives to keep their systems hack‐​proof. But government mandates for connected vehicles are both dangerous and pointless.
