When I am driving and stop at a light, I see the speed go down to 0 and then it switches to "Hold". But, when stopping at the same light during FSD, I see the speed go down to 0 and then it does NOT go into "Hold" mode. Is the car actually in "Hold" mode and it is just not showing it? If it is not in "Hold" mode and FSD stops at a light and I'm on a hill, is the car going to start moving down hill on its own?
