To save time. This car doesnt have good brake so i would smash into those walls with full speed then bounce to the track. U can complete a lap within lets say 1,19 sec by driving normally but with going off track and smashing to the walls u can get 1,10 sec. It make a lot of difference. This is the way to get those expensive cars in especial event for cheap(if it is recommended pr). And u cant use assists. U have to control it by urself.
