Re: Hard decision but Mercedes are probably right
Modern cars can stop in ten feet from surprisngly high speeds.
However, human reaction time is such that most people would have barely started braking.
The reaction time of an autonomous vehicle will be quicker than the majority of meatbags - otherwise it's not useful. It'll also brake or swerve harder, as it knows the car handling better than most humans do.
So the "will collide zone" in front of a moving autonomous vehicle would become notably smaller, and the resulting collision would happen at a lower speed.
It's still there though, no matter what you do.
Obviously there are some talented people who can often take a vehicle right to the limit, but they are rare and even they can't do that all the time. The AI doesn't get tired.
