Remember the time when you went for grocery shopping. Your hand was all full and you were not able to put your groceries in the back trunk of your car. Hard, right? The solution is here. There are some cars which open by using a motion detection sensor. the trunk of the ka opens just by you waiting your hand around it or when this sense the car keys in a pocket. This has actually helped a lot and made it easier for people to put stuff in the trunk. The hero here is the “Hyundai Hands-Free Smart Trunk”. It opens by itself the moment it sensors the driver is near.
