One of my relatives was killed by a drunk driver. Yay to laws about it.
You know, I almost posted something positive about DUI laws instead, but chickened out above and I shouldn't have. I don't care if you are on a bike or a car, you can still hurt people if you are riding drunk and cause accidents (although, yes it's more likely with a car). If you are drunk, you shouldn't be on the road.
While I agree with your final conclusion, most of the anti-alcohol stuff is bullshit, drinking age should e 18, and MADD as an organization is fucked.
We need to educate kids about alcohol and make it okay for them to have it responsibly at a younger age. Drunk driving is never acceptable, but most of the anti-drinking stuff is just terrible.
