Actually that's a bloody brilliant idea. In an ideal world, morality or enlightened self-interest would convince everyone to behave well. The real world falls far short of that ideal, but social pressure is often a powerful tool for filling in the gaps. You'd think "you might die" would deter drunk drivers, but it didn't. "Everyone will think you're an asshole" was more effective. Let's extend that to other forms of misbehaviour on the road. The point here isn't the technology. It's using the technology to save lives.
