Nissan goes some of the way
Nissan has just launched a car that detects whether the driver has alcohol in his system. It does this by sensing tell-tale signs of alcohol in the driver’s sweat, as he places his hand on the gear leaver. The car also picks up the scent of alcohol, and monitors the driver’s eye movements to ensure he is awake. Read more here and here. All very well. But if they really wanted to prevent accidents they would limit the car’s speed to a sober 60 km/h. This would no doubt save many more lives than stopping the odd drunk driver taking the wheel.
