The first is the best, my car key is a flat black card about 4-5mm thick which fits in my wallet. When I'm close to the car it senses the presence of the card and then when I put my hand into the door opening mechanism, I break an infrared or similar circuit and the car opens the doors. So keyless entry, then I sit in the drivers seat and with the card still in my pocket I press the start button whilst pressing down on the clutch. The car starts and the electronic hand brake disengages as I move off. So no ignition key and all I need concern myself with is setting off into traffic. At eurofoo, last summer the size and capability of the card really surprised some of my friends.
The other two devices are light sensing headlights, which turn on and off at dusk and in tunnels, again I don't need to think about the lights. Occasionally I put the sidelights on if the gloom warrants it. The last clever device is rain sensing windscreen wipers, they work well, but there is a setup issue. They rain sense on position 1, but you need to turn the car on with the wipers in position 0 and then turn them to position 1 to turn on rain sensing.
So three everyware devices in our car already. They are mostly seamless in their implementation and make the driving experience more satisfying. I have to think less about the process of driving and can concentrate on the more important issues like the view and road position. They also help in the anthropomorphism of the car, it feels more alive.
