Not quite Michael Knight talking to a car with William Daniel's voice, but Sarah Dodge, age 18, has a patent pending for starting up your car via your cellphone. It works by calling your car from the phone and entering in a 3 digit number to start up the car. Your '82 beater even calls you back and lets you know the engine is running.
Different from current remote starters, which need to be within a certain distance of the car to start it, this can start your car wherever both you and your car have reception. This can also be adapted to add remote unlocking features to cars. We're not sure why you'd want to start or unlock your car halfway across the country (wife lost her keys again?), but some people drink their own urine, so what do we know?.
