A radar on your car could tell you when you’re about to crash. Sensors
mounted in the bumpers and car doors detect the distance and velocity of objects

reduce the chance of injury to the car’s occupants. “It would tighten the
seatbelt retractor or adjust the headrest for a crash position,” says Martin
Kunert of Siemens, the company developing the radar. A BMW spokesman told
51¶¯Âþ that the company is interested in the system.
