I think you're making OPs point for them. Real drivers also crash into things. Self-driving cars don't have to be perfect all of the time. Inebriated and distracted drivers already cause disproportionate problems: self-driving, even one that makes a mistake once in a blue moon, is preferable than some dude on their phone who hasn't noticed the traffic in front of them has slowed down. (And 120 km/h sounds like highway cruising: precisely the sort of place where self-driving cars have a relatively easy time and "better than humans" is not very far off from where we are today.)
