I put the car in B for a while today, just to see. The mileage was horrible, so this is a possibility. But if you're not really paying attention, it is the kind of thing you could miss. I didn't take it on the highway, but I would think it would be even easier to miss at higher speeds. So don't feel bad. As I said before, I've done it twice now by accident.

The engine does not stay on ALL the time tho, as I incorrectly stated above. It shuts off at a stop.
