The Prius is awesome at what it does, but unfortunately, the engine stays on too long when the ambient temp is below 60F and the pulse and glide speed is too low at only >45 mph. Well to compound that double whammy my speed limit is 45 mph locally and hilly, and my gps speed at the indicated 45 mph is only 43.1 mph. I can get 70 mpg when the ambient temps are at 60F and traveling at 41 mph (39 gps), but I'm gonna get my ass ran over when I do that. So when I travel the speed limit it basically doesn't allow the engine to shut off and I get 40s-50. All to not be that pain in the ass Prius driver. So my solution is to make my own injector kill switch. Has anybody put it on the prius? If you put the Prius in neutral it locks the engine in the current position so I wonder if it would play nice with a momentary kill switch installed... I'm really thinking some crystalline window tint for summer and a kill switch would really push me through the next barrier in terms of mpg in my 8 year old prius.
