I don’t think it matters. I do think we’ll gradually shift to a large number of vehicles not needing a human driver in the front seat to control it. And it will be a significant enough number to lead to a societal shift in various ways.
I think it’ll be similar to remote working now. Not everyone can work from home. Some who can work from home will still need to go in occasionally. But the shift is significant and transforming.
Getting hung up on whether we can get ubiquitous level 5 misses the point IMO.
Are you not building in danger with anything below level 5? It's creating an environment whereby drivers feel that they don't need to concentrate as much on the road, we've already seen deaths caused through this in the trials by Tesla and Uber.
I'm all for tech that'll improve safety, but not sure whether this is a good step forward. Can definitely see autonomous only lanes on motorways or toll roads in the next decade, you can limit pretty much all factors there. Gov are clearly keen on it too.
