We've seen plenty of devices and technological advances that make your car more secure as well as make it more personalized. Fingerprint scanners, voice recognition, or the more basic door codes have all been used before. Now, students at the Advanced Institute of Industrial Technology in Tokyo, Japan are trying to use your butt to decipher if the person driving the car really is the owner. 

The seat concept uses 360 sensors that can "feel" and map the pressure from your booty. The students ran six tests, and the seat was 98 percent accurate in identifying the different people. Although 98 percent is pretty good, what happens in that two percent? Would we not be able to drive? What happens if people lose or gain weight? It's a decent idea, but still has some obvious kinks to work through.
