atfirst i was going to bitch at WTF this had to do with bitcoin. but instead i thought how to twist this into a bitcoin story.
imagine 2 racers at the startline. their onboard computers has just paid bitcoin into a escrow owned by the race track.. to get your input back and also the other guys input you simply need to cross the line first for the escrow to read your signed message saying "i won"
imagine a future where a computer onboard your Prius monitors your electric re-charge of the car and automatically sends microbitcoin payments to your utility company/local recharge station(previously known as gas station) to pay for the charge/refuel.
meaning all you need to do is plug it in. then imagine before entering the queue at the local mcdonalds drive thru. you order your food from your onboard computer, it sends the order along with your cars licence plate to mcdonalds. and all you have to do is drive up to the food window to collect your meal
toll roads auto paid for, where your car makes the payments simply by knowing the toll road address to pay. which can be done easily
All the smart phones have NFC so they will just send your phone a request for the amount I guess you stare at the request amount and just press accept if its right, like your saying though they will need to scan your identity QR code on your number plate and you will already have there's they will just pass you a new one out the window on a flyer if they need to or have a sticker on the drive through speaker box.
