John Book, the police officer that we're imagining has been living in Amish society since the 1980s, is probably used to shouting, "Throw me the keys!" to a fellow cop so that he can hop in a car and chase after bad guys and ruffians. That's why it will totally blow John Book's mind to know that now he doesn't need to do any such thing.
Many cars have remote ignition, which is particularly helpful on a winter day. With that gadget, you can push a button and -- kazam! -- the car starts heating up for you, while simultaneously locking the doors so no bad guys can steal it. But if you really want to keep your hands free to battle corruption, you should go keyless. With a keyless ignition system, you keep a key fob in your pocket. A sensor will detect the key fob's presence in the car and start; all the driver has to do is push a button on the dash and press the brake.
Crime fighters like John Book will be happy to know that this system deters car thieves because of the personalized nature of the fob codes and the system that reads them. Beyond just battling hooligans, this system could also have benefits for those with arthritis [source: Clarke].
