True, but you miss my point in referring to this. You still don't get to choose when someone else's mistake might harm you. Also, we as the public in general routinely trust planes with millions of risky flights despite not knowing anything about how well or safely they work, or how they work at all in detail. We accept that accidents sometimes happen nonetheless because that's how it goes with human technology that we've come to depend on. The important thing is that precautions are taken as much as reasonably possible. The same standard can be applied to driverless cars without getting fearful of them simply because of their newness.
