Looks like old O_O
For real though, I learnt a few tricks for this:
-
Try to turn as little times as possible, if you have to turn try to do it all in one big hold to avoid bigger time losses from smaller taps causing loss of traction.
-
For the 2 really sharp corners, slow down before hitting the brakes and drifting around them to lessen time losses.
-
Try to avoid airtime as much as possible, it slows you down a lot.
-
Also try to avoid hitting walls as much as possible, they bounce you off them in really strange ways and can sometimes flip the car causing the run to die.
-
When going over the forced bumps, try to hit them head-on instead of facing to the side a little, most of them will bounce you in the wrong direction if you don't.
-
Try to use the alternate camera to line up stuff easier (Pressing C), it helps a lot when lining up straight-line dashes for max speed.
