As a cheapskate, an hourly charge is exactly what would prevent me from using this for extended periods of time. Dense stop-and-go traffic is probably where I want autonomous driving the most. It's one of the most frustrating driving experiences for me. But it will be hard for me to switch on autonomous driving: Not only am I going to waste my time in traffic and my gas from idling, now I'm going to waste money per minute to let the car inch forward. I suppose there are situations where I would enable autonomous driving, like in an unfamiliar city or if I had been drinking at all (assuming it's safe and legal). This would probably add up to something like 10 hours per year, which seems like a huge waste of a big technological advancement.
