The Dope Man - endanger yourself all you want, but it is unconscionable to be driving in that state. Even if you know the area, it's late and there aren't many cars out or whatever excuse you'd make, you could kill or injure someone and there is simply no excuse. It's disgusting seeing you relay that behavior on a harm reduction site without a shred of guilt or remorse but honestly not shocking.
I'm sorry if this comes off as harsh or judgmental, but as someone whose life has been greatly (negatively of course) affected by impaired driving multiple times, it's difficult for me to see the subject discussed in such a cavalier manner.
A former OD mod was passed out from heroin (among other things) in a car recently and caught by the police. Even if the car isn't running you can get DUI/DWI charges so even if you aren't willing to consider the risk of killing someone else, consider the fact that next time you pass out in a car after driving fucked up, you could easily end up spending some time in county and/or losing driving privileges for a while.
Congrats on the new job, cloudy! I hope it goes well
