Decisions ,decisions.
Most of the talk about humans driving and making moral/ ethical/ informed/ intelligent decisions in the event of a sudden appearance of a pedestrian or anything else in their path is largely crap.
In my 50 odd years on the road I have observed that most people usually try to swerve to avoid most sudden obstructions without thinking, those that don't are usually drunk, stoned or cretins.
So probably whatever Mercedes come up with, will be at least as good as most people and better than the drunks, stoners and cretins.
