For me i hide a key in the car really well. Second one goes in my pocket of the tether. Then i leave a door unlocked. If they want anything then by all means take it just dont break the damn windows. I make sure the cars cleaned out of most anything valuable. Ill even make sure theres a hefty handfull of change.
Doesn't matter how many steps you take, if someone wants it they will take it regardless. Be smart, but dont live in Fear, your session will be ruined if your constantly worried. That or let your friend drive.
