The reaction time is actually an interesting question. Reactions in humans which do not require thought/planning can be quite quick, and the human vision system is /very/ quick, especially for movement. How fast is the vision system in a Tesla? Not only frequency, what's the latency from vision change to decision? My guess is the Tesla is faster, but by less than an order of magnitude. I would not be surprised that it's slower for some cases. But I really don't know.
