Yes indeed. I don't think it'll be easy at all. Trying to stop intoxicated driving is difficult enough, and that's usually driving that happens "after hours". So this would be ten times more difficult.

I suppose, in theory, most of the time forcing the use of some sort of alternate transportation would work, although we'd have to figure out how to make it cheaper. We often drink close to where we live, and work far from where we live.

If it was up to me, I'd delay this further and do more research and get more smart people coming up with ideas on how to solve these problems, because it would be worth trying to fix. But then again, there are so many problems we should be tackling, this is a relatively minor one.....
