It resets itself back on (by law) every time you restart the vehicle. A couple days ago mine failed to restart itself, instead shifting into neutral (!) and rolling partially into the intersection I had intended to pull out into. It wouldn't shift into park because it wasn't "on" (?) but also wouldn't turn "on" (!?) as traffic started to barrel down on me. I'm honestly not sure what sequence of pushing the "on/acc/start/off" button, the "park" button, and "drive" button got it back running, but eventually I was able to go.
It was a somewhat stressful experience, but I guess I saved ~10-15 seconds of idling trying to leave work?

- giantg2 3y ago"It resets itself back on (by law) every time you restart the vehicle" That's what internet searches and fuse pullers are for. "but I guess I saved ~10-15 seconds of idling" That's where the calculations get tricky. There's usually a time limit for which it's less efficient to stop the engine (about 4-7 seconds). So to calculate fuel savings, you actually should only count idle fuel rate times the number of seconds above that cutoff, then you also have to account for less efficient stops under that rate (maybe just subtract them from your seconds above so you get a net seconds beyond breakeven mark). I'm not sure any the systems track it that way, it's just how much overall time the car spent in the stopped mode.
- ultrarunner 3y agoI used to just turn my car on and off when I wanted it on and off. Now I have to do internet searches and figure out how to modify (break) some black box system to keep it from creating minor safety situations or inadvertently undervolting the stupid touch screen so my stereo no longer works (requiring a turn-it-off-and-back-on-again that I … you know, can no longer do).
