You say that like 3-5 wouldn't already be insanely good. Even 1.1 would be a huge decrease in pollution. 0.4 and it might still be worth it due to fewer casualties and the ability to safely multitask.
I'm not talking about whether it would be good. I'm sure it would be great. I'm talking about whether the introduction of autonomous cars will result in everybody ditching car ownership and using companies like Uber for transportation, which a lot of people seem to think is a given.
