Car chase scenes in which the bad guy's car hits another car (usually stationary) in such a way that would normally just be a nasty impact, but instead takes a leap and rolls like a stunt plane in mid-air before crashing down on its roof or one side. Yes, of course there was a ramp.

Similarly, any vehicle leap in a chase scene that would easily take out the oil pan and the front suspension, but the car remains completely viable for another mile or more.
^^^ Nice skidpan, bro!
