This is an embarrassing story, but one time I left my car running outside a coffee shop while I had coffee with a prospective employer for about an hour. When I got to my car it was no longer running but it was blisteringly hot because I had left the heat blasting, and there was a note on the dash that said "I turned your car off, I hope that's ok, your keys are in the console". So yeah, sometimes and in some places stuff doesn't get stolen when it could.
