Fuck i hate that. Each manufacturer seems to have their own logic, and it's not well tested. Got locked out of mine once while it was parked and idling, i don't trust it - will open the window up just in case if I have to exit it while the engine is running.I had a rental car last year after the accident, was going out and warming it up, sweeping snow off it and the fucking thing locked. While running. My truck won't let me lock doors while it's running....
