It's dark. There's a box. It beckons. You stick your finger in and curl "your index finger towards you in a summoning motion". Congratulations, you've just started your car.
Two students, Zhao Wencai and Li Zhoumu, invented this gesture-based car interaction as a presentation for the third China-International Road Safety Expo. Not only can you pleasure your car to start it, you can shove your middle finger in there onto a fingerprint scanner to read how high your blood alcohol level is. Another possible use is as a security system, so the car wouldn't start unless your finger belonged to one of the registered drivers.
