They need to. Include ALL
They need to. Include ALL combustion engines not just passenger cars and light trucks. I know there have been many studies, but I’d presume about 80% of the noise and air pollution comes from small engines and large trucks, not the class of vehicles that is already abiding by all means of stringent air quality standards. It’s time to get rid of the non-stop droning and abominable pollution of landscaping equipment, for which battery-driven products have been available for well over a decade. If we can’t even transition these small items to battery power to get rid of fossil fuels how can we possibly transition the larger ones?
