If it is illegal to drink and drive, why do bars have parking lots?

Drunk Ass in Dublin, If bars didn't have parking lots, then where would you be able to pick up drunk prostitutes after a night of Jagerbombs and blow. Yes, eliminating parking lots and alleys near bars would decrease the spread of herpes by 167%, but it would also leave you sad and lonely on a Friday night. And just in case this "no parking lots for bars" idea ever takes off, I would invest in any company that makes hand lotion and/or porn.
