I mean, you say this as though Banning Self Driving Cars is some controversial policy action, rather than just literally the current state of the law in most areas. The point is that it’s weird to legalize them when they’re not ready for prime time just because you figure “the future is coming,” because usually we make laws around technology based on how the technology works in the real world, not how we figure it’ll probably work in the hypothetical inevitable magic techno-future.
