The thing I find the weirdest about this is that even when you've (at least visually) reached max speed on concrete, your braking distance still goes up after that. You reach max speed in less than 10 seconds, but braking distance increases for another 20 seconds. This does not make any sense to me ...

The car braking distance is too long when driving on concrete compared to grass, and it depends on how long you have been driving on concrete for. The longer you drive on concrete, the longer the braking distance. I got up to 3 times the braking distance compared to grass, while the car is not much ...
