 In most experiences that I've had, if I get to a traffic light and I want to see if start-stop doesn't work, pop it into neutral. Just got to remember to hold your foot on the brake so the car doesn't roll. But, you know, sometimes popping it in neutral will take it away. I personally have an issue with start-stop real quick because I just worry that on an older vehicle, the abuse I'm putting on the starter, how good is that battery?
