X-Treem Aerobraking

The best way to slow a road vehicle down (in an atmosphere). While coasting at high speed, the driver thrusts open his/her door and holds it at full extension until the car comes to a stop. NOTE: this does not work on those fancy cars where the doors open upwards, but still looks cool.

This becomes extra awesome when the passenger is holding their door open at the same time - the car becomes like a giant metal falcon of justice (GMFOJ), swooping silently to a halt.

This has been tested at speeds of up to 60km/hr, and is a terribly ineffective way to slow a car.
