Thats not the argument at all. In the attached paper, the author suggested validating driverless vehicle safety within constrained environments, like using beacons on roads.

You make an argument like you have a hammer in your hand and you are looking at a row of nails. I'm suggesting it is short-sighted to look at the problem from only that lens.

For instance, with a more holistic lens you might explore the right place for humans drivers vs autonomous vehicles. You might simulate entire cities from the ground up, specifically optimized for transportation. What if the real breakthrough in transportation systems actually comes from the ability to quickly construct / deconstruct roads? Or dynamic city zoning? Or any number of non-vehicle innovations? What if we were actually optimizing for safety in transportation and not just trying to compare machine ability to human ability in limited contexts?
