Your wheels locked up. Ease up your brakes or just turn on the ABS.

Your wheels locked up from coming over the hill. This is a common issue that effects many cars and drivers. When coming up to a turn that is just over a crest, its usually best to brake early as you may have to let off, then get back on if your brakes lock up like this. As for the spinout at the end, just too much throttle on top of your tires either being to hot or unevenly heated from the skid, depending on the physics of the game. When your tires spin like that on takeoff, ease off the throttle a bit until you hear your RPMs stabilize or start to drop and it will be much easier to prevent a spin
