Awesome system that joins up all the dots from your car to your phone. #ifttt
integration to turn the lights on when you arrive home and automatically map where you parked your car plus tons of other recipes to automate your life (tweet your mates when you arrive at the pub? Email the mechanic if the engine warning light comes on?)
It's even able to send out a crash alert if you have an accident. Just need to wait for it to come to Europe now!
