If you drive a newer Mazda vehicle, you're probably familiar with its "i-stop" feature. The Mazda i-stop technology is known to some drivers as "idling stop" or "stop and go". This technology helps shut off your car's engine when you come to a stop and starts it up again when you are ready to move again. While the car turns off when idling, it helps to make Mazda vehicles more fuel-efficient, and most people don't find it all that intrusive, but some drivers don't like the idea of having their vehicles shut off whenever they pull up to a stop sign or traffic light.
