Cars that won't let drivers drive drunk

Forbes Magazine is reporting that Toyota is developing a new device that will be able to tell when drivers are drunk and prevent the car from driving. The same device will have the capability of slowing down and stopping when a driver falls asleep behind the wheel.

So, how could you use this news article in a classroom? For me the question is about responsibility and where responsibility lies. Can you imagine a driver suiing Toyota because he fell asleep behind the wheel, the car didn't stop and he got into an accident? Would such a suit have legitimacy? I'm going to teach religious school now, but I think I'm going to ask this question to my students. Perhaps, they'll blog about it afterwards.
