This is good, though:
Quote:The system could also kick in if the sensors detect abnormal steering, or if a special camera shows that the driver's pupils are not in focus. The car is then slowed to a halt, the report said.
I like how it has implications beyond drunkenness.
OK, the "slowed to a halt" part makes me a little nervous. They're on a freeway, they're drunk, they're oblivious, the car slows to a halt in the middle of the freeway and they can't start it again...
