The numbers say let Robocars exceed the speed limit

I’m often asked whether robocars will keep themselves to the speed limit and refuse to go faster, unlike cruise controls which let the driver set the automated speed. In many countries, the majority of human drivers routinely exceed the limit which could present issues. On the other hand, vendors may fear liability over programming their cars to do this, or even programming them to allow their human overlord to demand it.

While the right answer is a speed-limit doctrine like the French Autoroute, where the limit is 130 kph/80 mph and few disobey it, until we can come to that answer, the math suggests that travel might be overall safer if the robocars are allowed to speed in the same way humans do, at the request of humans. And indeed, that is how prototype implementations have been built.

I felt this subject (and related subjects about how cars should deal with laws that are routinely broken by human drivers) deserved a special article. Read about it at:
