Just saw this clip where Ford integrated Smart Tech in their cars. I guess its old news, but I think it is really clever and obvious progress in automitive vehicles. Driver key recognition that customizes your experience. Parents have full priveledges, kids must buckle their seat belt to access the radio, there may be a volume limit on radio or speed limit on car in general. A bit of a big brother thing but cool.
I think I mentioned the Fiat Eco:Drive application before. Fiat developed a USB based app. which analyzes your drive and gives you tips which enhances your performance and makes you more Eco friendly. Clever clever clever.
