While I like the idea of Hold mode, not regularly using the brake will cause the breaking reflex action to fade with time. You really want to have a good "slam the breaks" reflex if you drive a car On the other hand, maybe Tesla feels their automatic systems will break better than humans and this is not really a problem to worry about.

I'm not a Tesla driver, but I would guess the Hold mode doesn't turn off "slam the brakes" when the driver needs to stop fast.

I think njarboe feels that it is the human reflex to 'slam the brakes' will fade if the human doesn't use it enough in 'hold' mode, not the mechanism in the car.

Correct. Moving your foot from the accelerator to the brake is a much practiced motion and your body can do it very quickly without much thought. I rarely use cruse control, so when I do and think I might want to brake soon, I get nervous. I don't really know where the brake is. At that point I put my foot back on the accelerator and now my body knows how to hit the brake again.
