It interferes with my regular driving because my car has stalled twice in traffic the first three weeks I've had the car. I now always shut it off when I start my car. To me, getting slightly better gas mileage does not equate with the possibility of not knowing when I'll have to manually restart the engine but knowing for sure that sooner or later, I will. That possibility occurs not because of anything I've done but because the manufacturer has provided a feature that defaults to a system that occasionally fails to work.
I know that pushing a button to override this feature when I start the car is no big deal. But I do know that I shouldn't even have to do that. For that reason, I definitely want the update to the last user mode.
