I look forward to riding my bike 10mph in front of driverless cars.
This is one of the few things that excites me about driverless cars. People should be driving below the limit (and the limits should be about 10mph lower in a lot of places) for pedestrian safety. The fatality rate drops precipitously around 20mph.
Instead of mad honking drivers, the car will sniff your smartphone's Bluetooth address. Computers you go near will recognize the smartphone, know it's you, and they'll start crashing programs and slowing down the wifi...
I agree that city driving is a more complicated issue. Freeway speed limits are a much easier case, but maybe I'm just missing driving on the Autobahn.
