Was thinking about this the other week
Was thinking about this the other week while inflating my car tyres at the local Tesco and I was wondering to myself how long it would be until we had cars and services where you could simply pull up beside a pump, and not only would it locate your fuel filler port and fill up the tank by itself, but it would also locate your tyres and inflate them to the relevant pressured based on some kind of QR code, and maybe there would even be a small secondary port next to the petrol inlet, which could be used to automatically top up your wiper fluid and antifreeze at the same time.
