The highside is one of least common but most spectacular auto racing incidents. It happens on motorcycles all the time because motorcycles have only two wheels, but getting a car to flip over is not so easy. Most of the incidents I’ve cataloged involve a high berm/kerb. Why anyone would intentionally put such features on a race track is beyond me. Low kerbs can become high kerbs if the dirt on the outside of the track gets worn down enough, so watch out for that. When approaching a corner with a high berm, be extra careful. The tenth of second you lose by driving under the limit may save your car. Oh right, the TLA for this is HBH (high berm highside or HKH if you prefer kerb).
