ehhhhhh...PRETTY neat...but doesn't seem to be straight out of the movies like the title destribed. The fact that it was an iThouch (or iPhone) didn't matter, it could have been a desktop in his house.
All he has is a Server in his truck, and that server is connected to the internet and to an output device (being the 6 wires from the car that control the doors, "Boot" or trunk as normal people call it, and the Engine ignition. Those are 3 items that are all push button...either on or off...yes or no.
They did that on Big Bang Theory...just with a lamp.
One plus though...he has a super modded auto car starter that can be anywhere instead of just within 100 yards. That would have to get you laid if the RX-8 wasn't working for you.
