They were racing down a Mexican highway when all of a sudden the girlfriend of the driver yanks the hand brake. The car crashes and this video reveals the point at which the car actually flips over.
This is an example of how street racing can be very dangerous, especially when your girlfriend is in the passenger seat.
While they were racing with two bikers, the wheels suddenly stop.
Apparently the passenger in the car pulled the handbrake while the car was speeding and then the car flips over, hitting a guard rail, then going back onto the highway. No word if the passengers were injured in the wreck.
