Hello! New cars have this fun feature of turning your car off when you idle for too long. Whenever I drive a new rental care with the feature I always turn it off because it drives me nuts. I started thinking about it and I thought that idling (at least at a stop light) is more efficient than starting your car again since it takes more fuel to start. Why then do all of these new fuel efficient cars have this feature? I would assume it’s more fuel efficient since they all have them now, I was just wondering how?
Thanks!

The math has been done, and the fuel to start a car is roughly equivalent to seven seconds of idling.
Sure, in two seconds of starting it burns seven seconds’ idle, so it’s certainly faster than normal idle fuel consumption, but not *that* much.
