Yesterday we went to the dealer for oil change, was in traffic, multilane road, stoplights. I noticed the new red car beside me at light was always just restarting as I drove away. Was at least a 2-3 second delay at every light. My car ... already running ... was in the go mode and just went. I was just waiting for solid green and watching the traffic for "runners", and noticed the red car "hanging back". I saw that I was clearing the intersection every time before that red car began moving, and I was NOT jumping the lights. Usually I started moving just about time I heard the red car's starter, just by coincidence. Pulling into traffic from a side road or driveway, I can see that 2-3 second delay being the difference between "rear fender vs no rear fender".
My starter will live an easier life as well as will the battery.
