Now I’m just imagining endless gridlock because an AV randomly stops mid highway, and all the other AVs reasonably stop, creating waves of backup. And this happening on a fairly frequent intermittent cycle.

Big is different, and scaling this kind of thing to majority of vehicles on the road can cause all sorts of interesting problems.

I’m not saying it’s inevitable; sure, we can and most likely will improve things on the long road to majority AV. This simply occurred to me and I hadn’t seen it articulated before so thought I’d share.
