wouldn't be hard to do but at best its a gimmick with the potential to be really annoying. Every time you want to start the car you would have to wait for the pc to boot. Doesn't seem bad but if you run into a shop, get fuel or anything like that you have to wait the 30-60 seconds before you can start the car. As security its useless as all you have done is disable the starter. A simple push start would get the car going quicker than the PC would boot.
