For me this is the important part. Too many people already drive far too distracted. Imagine giving many of those same distracted drivers a great reason to ignore what they're doing even more. Very frequently when I'm stopped at a traffic light I'll see the person next to me on their phone waiting for the light. Would we trust that someone doing that would lookup when their car starts driving into the intersection?
I really do want self driving cars to be a thing but I wish we were going about it a bit differently and I wish other people who wanted it didn't play things down as much as they do.
