Please, tell me about all the cars right now that avoid hitting pedestrians and bicycles and wheel chairs. If impact immenent (7th grade algebra) then stop.
What's your point? You're saying you could apply 7th grade algebra to this problem and make these cars considerably safer, but that the people working on it now just don't bother? Because they're evil? Or what?
I don't know what to say.
Coming in late, but I think you're misunderstanding the suggestion, which was to make pedestrian avoidance standard equipment on all new cars, not just autonomous vehicles.
