You guys can just turn the stop/start feature off if you’re afraid of it you know.
It’s about emissions output. Lots of CO exiting the cars when sitting at stops. Lots of criteria has to be met for it to happen and if one of the needs isn’t met, it won’t happen. Won’t happen with a cold engine, won’t happen if the ambient temp is below a certain point, won’t happen if you have the AC or defrost on, etc. The list goes on. I think ford has 31 different criteria that have to be met for them to shut off at stops. But like I said, you can just turn it off too.
