How about not drink if they know they have to drive later. Drink only when you have alternative means of transport, or a DD.

You don't design city policy on the assumption everyone will behave responsibly. That assumption is false, and while education can amelliorate the issue, it's improtant to know some people will make bad decisions. Having good public transportation makes DUI a lot less appealing, and as such it's an important policy in a city where it's easy/normal to get drunk.
