Most human drivers tend to over-estimate the consequence of a collision — it’s common that swerving to avoid a wild animal poses a greater danger than hitting, for instance.

However, what a robocar can do that most humans can’t is organise the clean-up, and that’s hundred times more important, because presently, hundreds of cars will pass that debris.

Let’s say you have a radar under the chassis (not unlikely given Telsa’s latest PR issue): the car OS can warn the authorities instantly with an exact location; images from several cars can be compiled to form an exact estimate of what it is. All car with significant connectivity can be informed that this lane is closed a small portion before any physical equivalent (orange cones) has time to be set up, possibly allowing a safer clean-up if the (connected) highway detects that all cars in the next x minutes have been warned, and a brusher drone can be dispatched.
