I’m in Japan this week for the CEATEC trade show, and had a chance to experience Nissan’s Advanced Technology Center in Japan. They showed us a car that detects alcohol in the air, on your breath, and in your sweat, and won’t let you drive until you sober up. The car can also detect inattentive driving or when you’re becoming sleepy, attempt to wake you up or get your attention back on the road, and get you off the road as soon as possible.
Nissan also showed us their Safety Pedal, which detects when you’re coming up to a car too fast and automatically hits the brakes. They called the detection their "magic bumper." Cool.
