content: We will absolutely still need appropriate bike/ped infrastructure built to separate traffic. A cultural shift still needs to occur away from a car-centric mindset to a public/bike/ped mentality. The same human element issues will still plague us with self driving cars - 'Driver' vs. 'Cyclist' mentality. That being said I keep hearing these stories and seeing videos of terrifying interactions between drivers and cyclists. I live in a mid-to-large sized city (almost a million people), and I have never had issues with drivers. They provide plenty of room when passing, most slow, some folks wave. I wave to people after I make a left hand turn and block traffic. I commute daily with one section of my ride occurring on a 45+mph two lane road with no shoulders or bike lanes. I try to be courteous to the drivers, and they seem to provide a courtesy back to me. I guess what I'm trying to say is not everyone's commute is fill with rage-fueled drivers! :)  We still have to fix our infrastructure and cultural outlooks though, because those horrible interactions you talk about DO exist and self driving cars wont completely mitigate that, though I would like to think it would lessen it.
