at the last hairpin left turn, get ur car on the grass inside, then keep ur car on it and turn .don't go out of grass .
after going a few distance, u 'll get the message:wrong way no time!
ok! go straight and ignore next turn. then full throttle and see how fast u r!
i don't know why either, as i also suffer this problem -----it seems the car is keeping on running on the grass even when u go out of course.. so.............
