Interesting to note that cars of next decade will be one's smart terminals and would allow the drivers and / or passengers to interface with various devices at home or office and transact. This means, travelling is not a waste of time, one can be at work while driving!
Even cars and the humans can be embedded with devices and technology that will authenticate the driver / passengers based on one or more of various personal traits, before allowing to drive the car.
