Any car owner would not dare to ruin the paint in their car. To think of crashing a car is unlikely for them since they have invested in their cars and they don't want their investment to just fly away.
However, this game makes you enjoy crashing other cars. Well, at least, other cars on the road. Drive your car as fast as you can till you reach the finish line. Usually, that will get you to the enxt level, but in this case, it won't help. You need to earn more points that the points indicated in each level to be able to unlock the next level.
