I'm not commenting on the morality of drunk driving. I'm commenting on the effectiveness of just fucking them over, that being, not effective at all.

There's this thing in the mainstream where people feel like the best way to handle people doing bad things is to just pummel them into the ground as much as possible.

While that might feel the most justified, that doesn't actually solve the problem. Suspending licenses doesn't stop drunk people from driving, because cars are more or less a necessity.

So, knowing it's a necessity, we have to design the car around that and enforce safe operation by an alcoholic.

Which is a stop-gap solution. A better solution is making cars not a necessity. But until then, we should do the stop-gap.
