Sitting in traffic is much more inefficient than one would think, though if you're cruising on the interstate at 70 mph you would obviously be correct.

Why not take a bike ride to the train and then ride the train in? People wanting autopilot driving cars....that's literally what a train does, complete with wifi.

My commute, in a city with excellent public transport (but also a lot of traffic), is 35min by bus vs 15min by bike. So... yes they would.
