> There's also the option to reduce speed as much as possible, aka break hard, that a computer can do a) earlier than a human would b) much harder than a human would.
a) A computer can initiate braking a small fraction of a second faster than a human, which is great but not such a huge difference in braking distance.
b) A computer cannot brake any harder than a human, certainly not "much harder". The max deceleration rate is traction-limited, which any remotely modern car (last ~25 years) can easily sustain with an untrained driver thanks to modern ABS.
(As a side hobby I instruct in car control and accident avoidance clinics. Blindly braking hard is not often the best answer.)
