I know in my experience, there have been times when I drink, go to my car, and realize that im not capable of driving home, and if I do then i am a danger to myself and other people, and could end up in jail.
so I nap it off in the car. Where else am I going to sleep it off? Where else should I go? Knowing that you can still get in trouble for sleeping in your car, which was the responsible thing to do, could lead someone to say "fuck it if i can get in trouble fir this i might as well try to drive"
I guess im lucky I didnt get caught, but if I did, it would have been bullshit for me to get in legal trouble for making the responsible decision to sleep it off instead of drive
