you guys must live in bum****, nowhere if you think leaving your car unlocked with 4.5k sitting out for 10 minutes (not a short amount of time by any stretch of the imagination) is any different than leaving it on a bar.
it's so absurd that it borders on trolling. I'm acutely aware any time i'm carrying that much cash around. the only people that careless with that amount are those who don't care if they lose it.
GL to OP ...
