Cool Crash Test methodology

I have always wondered how cars were driven at controlled speeds during crash tests. Turns out there is a system of pulleys moving the car at the required speed!

Howstuffworks "How Crash Testing Works"

There are 15 high-speed cameras, including several under the car pointed upward. They shoot around 1,000 frames per second. Next, the car is backed away from the barrier and prepared to crash. A pulley, mounted in a track, pulls the car down the runway. The car hits the barrier at 35 mph. It only takes about 0.1 seconds from the time the car hits the barrier until it stops.
