> The vast majority of drivers are on familiar routes and are not navigating via electronic means. I've been rerouted due to an accident many times, and I've seen the detours get backed up because of people taking more optimal routes (without traffic being redirected via other means). I'd be curious to see more data on it, but I would speculate it's less than the "vast majority". > Better question: How are the autonomous cars doing? Are they parked by the side of the road unable to navigate without cell coverage. Yeah, that falls under my point about Uber/Lyft/taxis. I would speculate there is broader impact from those vs. autonomous cars (that are probably still relatively uncommon).
