I've been wondering, some new cars have a system called "passive keyless entry" where you have a small transponder on you, and the car will automatically unlock for you as you approach it, and lock when you walk away. Theoretically, you can just walk up to your car, get in (no ignition key rerquired), press a button to start the car, and you're off!

Now I realize bypassing the ignition could present all sorts of wierd problems, but perhaps there are companies that make an aftermarket system like this? Just curious is all, it's really cool!
