Come back to your other car to find it locked and running? I'm out of town with a rental car and I've left it parked and running no less than 6 times now. Most recently I came out of a grocery store after 30 minutes and there's my Dodge Charger, locked and running in a parking spot, my brother laughing at my seeming incompetence. I'm so used to just parking and getting out that I keep just parking and getting out. The Model S has ruined the way I car.
