Umm.. yeah, I've probably owned my TCH longer than all but a few here, I am in fact aware that when the battery gets low enough the engine comes on. How long do you think it takes to grab something? Heh. I love my car, do you really think I'm going to leave it on unattended long enough for it to be obvious it's sitting there running and empty? Give me a little credit! Upstairs, inside, grab, back down with a couple of locks in between.
