It's not a black and white thing. No driverless car, nor human driver, can claim to 100% avoid accidents, even those that are theoretically avoidable. But some can be better/safer than others. Most likely, though, the way competition will play out around this issue is how conservative the decisions the vehicle makes will be. So a "lesser" vehicle might come to a complete stop at a crosswalk, while a better one (as well as any reasonable human driver) might be able to calculate that it can safely drive on through because that pedestrian is well way out of the way. Both vehicles can be equally safe, but one gets you to your destination a lot faster because it is better at accurately estimating collision risk, so it doesn't have to compensate by sacrificing timeliness. Competition is important.
