That must have been what the PR folks at Volvo were thinking after trying to demonstrate to the media the company's collision-avoidance system, which uses forward-looking sensors to automatically slow a car before impact if the system reads that the brakes are not being applied correctly. They launched an SC60 out of a safety tunnel at 30 mph, piloted by only a safety dummy, aimed directly at the back of a parked truck.

Any guesses as to how the test turned out?
