Google had fail safes which failed. What if a million cars pull over to the left instead of the right as a failed failsafe? Willing to risk your life?
I'm also a biker. In 2013, 4,735 pedestrians and 743 bicyclists were killed in crashes with motor vehicles. http://www.pedbikeinfo.org/data/factsheet_crash.cfm
In the future when self-driving or at least augmented driving is commonplace, I hope that number will be a lot lower.
