You can still change a tire, jump start, change a broken fan belt, repair and/or change a leaking hose, change a light bulb, change the wiper blades, change a fuse..........all sorts of little things like that on the side of the road. You can still change the oil, change the transmission fluid, change the spark plugs and coils, add washer fluid, install a backup camera, and perform minor service in your driveway. Even with a sophisticated computer, bolt on parts are still bolt on parts. Don't let the sensors intimidate you. It's not like making roast beef in a microwave.
