Researchers at Cranfield Impact Centre and Nissan Technical Centre Europe has developed a crazy mixture of technologies, finger scanning and adjustable airbag and seatbelts, to try to save lives. It's quite innovative, actually. In accidents, treating different people with the same amount of seatbelt tension and airbag deployment can result in injury from the safety devices. (This is still a far better fate then not using them, so buckle up.) They are using an ultrasound scan of the finger to determine bone strength and adjust the car's features accordingly. Our sis, Engadget, has the lowdown.
