How can I live in my car HELP?

my lease ends March 1st, I had told owner I’m giving her the keys by 3rd wk. No owner is replying me back and most want high credit or charge 3 deposits. I applied to one place last week but it got rented today. I only have one appointment tomorrow but like always owner will say he’ll need interview more people & it’s not available til 25th. i sent texts to 30 places already & no luck.😔I plan rent storage next week & move in my car. Sleep there. Is it safe sleep inside a car with windows up? I won’t find an owner to accpet me give me the keys.😓I’m crying. Everything is in boxes the room is halfway empty
