Sleeping in a car isn't illegal necessarily, but there are increasing popup communities that settle in empty/low traffic lots and live out of their vehicles. Like most of America's problems, our politicans are sending police forces to "clean up" the effect, instead of trying to solve the cause.

Here's an article on Vehicle Residency https://www.thenation.com/article/society/homelessness-vehicle-residency-housing/

Sleeping in your car in public is not allowed in Germany either

In some places, parking lots are monitored by security and you'll be kicked out if you're sleeping in your car in the parking lot.

I see a lot of areas with "No Overnight Parking" signs or something similar, so they don't make sleeping in your car illegal technically, but you can't stay there over night.

Often times it's loitering charges, loitering being a fancy term for "being out in public whenever it displeases a person of authority". Sitting on a public bench, having a picnic, walking on a sidewalk, sleeping in your car, whatever, all of those can and will get you loitering charges depending on your exact location in the United States.

Then you have public intoxication charges which on paper are only supposed to apply if you're causing a public disturbance (despite disorderly conduct already being a charge for that, public intoxication just makes it more severe), but in reality it's mostly used to harass drunk people who couldn't get a ride home, or uber home, and decided not to drive while drunk. I wouldn't be surprised if you had a higher likelihood of getting arrested for public intoxication while drunk walking/public transporting home than of getting arrested for DUI while drunk driving home. But public intoxication and even DUI can also be used if you're sleeping off drunkenness in your car, while the car is turned off.

Less actually illegal and more that the lots are privately owned and the owning companies can have you removed from the lots of they don't like what you're doing.

First time I’m rooting for the geese, usually they’re the assholes.

There should also be some extra sauce on the sentencing for anyone who carries a badge or position of legal power and abuses that.

Solo Leveling Penalty Game huh? Damnit, I'm in! What do I get for being someone in HR denying someone a job for reasons of "I just wasn't feeling it."?

The idea of secret laws seems incompatible with democracy

Yeah, in an article talking about how news stories about crime often show pictures of tents, they pointed out that the photo is of a crime scene, but the crime was not committed by those living in the tents.

Actually Walmart does not allow it, but most stores don’t care. My local one had a guy unalive himself in his car surrounded by other multi day parked cars. It took them 3 days to see all the others cars leave and he was inside. So now they enforce it. Understandably so.

When I was in this position in my life I used parking lots of 24 hour gyms never once got hassled or disturbed.

Unless it's one of these

Whoa, all of us lazy people doing light drug use catching strays
