In the bluntest possible sense, who cares if we can make roads safer? Solving liability in traffic collisions is basically a solved problem through the courts, and at least in the UK, liability is assigned in law to the vendor (more accurately, there’s a list of who’s responsible for stuff, I’m not certain if it’s possible to assume legal responsibility without being the vendor).
