Regulating a complex new technology is hard, particularly if it is evolving rapidly. With autonomous vehicles(AVs) just around the corner, what can policymakers do to ensure that they arrive safely and smoothly and deliver on their promise?
The immediate goal is to make sure that AVs are safe without preventing innovation. In America, experimental AVs are allowed on the road in many states as long as the companies operating them accept responsibility. Chris Urmson of Aurora says American regulators have got things right, working closely with AV firms and issuing guidelines rather than strict rules that might prevent the progress of the industry. “It’s important that we don’t jump to regulation before we actually have something to regulate.” he says.
On the other hand, Singapore’s government has taken the most hands-on approach to preparing for AVs, says Karl Iagnemma of Nutonomy, an AV startup that has tested vehicles in the city-state. For example, it has introduced a “driving test” that AVs must pass before they can go on the road. This does not guarantee safety but sets a minimum standard.
Elsewhere, regulators have permitted limited testing on public roads but want to see more evidence that the vehicles are safe before going further, says Takao Asami of the Renault issan-Mitsubishi alliance(联盟). “Simple accumulation of mileage(里程) will never prove that the vehicle is safe.” he says. Instead, regulators are talking to car makers and technology firms to develop new safety standards. Marten Levenstam, head of product strategy at Volvo, compares the process to that of developing a new drug. First, you show in the laboratory that it might work; then you run clinical trials in which you carefully test its safety and efficiency; and if they are successful, you ask for regulatory approval to make the drug generally available. Similarly, autonomous cars are currently at the clinical-trial stage, without final approval as yet. It is not possible to prove that a new drug is entirely safe, but the risk is worth taking because of the benefits the drug provides. It will be the same for AVs, he suggests. After all, nowadays human-driven vehicles are hardly risk-free.
