This fall Nissan announced that they developed new technology with cameras and radar that senses dangerous situations and tells the driver exactly what to do to avoid the hazard. If the driver fails to act in time the car takes over and handles the steering and braking duties. Too bad they don't make locking underwear that senses dangerous situations when you're drunk, too infatuated or otherwise unable to act :-) Come to think of it, it would be real handy to have something like that for your pets.
