Like I said; there’s only so much you can test on a closed track. At some point you must start doing that in the real world. Pedestrians getting killed by experimental self-driving vehicles is not an actual issue we’re dealing with right now but more like a theoretical possibility of what could happen in the future. There are only a couple of such incidents recorded ever. That’s not a good enough reason to not continue with it.

What I mean by them now being the worst they’ll ever be is the self-driving technology itself. It’s constantly improving and the trend is towards better. The technology we have right now is the worst it’s ever going to be.
