If they're too drunk I'm not sure they would actually look at their key ring and think about it.
It's really sad to see these people get in their car because they've got jobs and families and they tend not to think about that because the alcohol has taken over.
The cops are out at every bar just waiting for you to get in your car and drink and drive.
I hope that maybe it just gets them to think there are cops out there and they are going to be cracking down more on drunk driving.
