And noise pollution! Even electric cars (which are quite heavy and produced a lot of tire wear) create loud roaring at moderate to high speeds for anyone the car is passing.
EVs have the benefit of regen breaking though, which means less break dust contributing to the pollution.
Less than a vehicle of equivalent mass, sure.
EVs are broadly comparable to the ICEV equivalent. We're talking 10-15% difference, sometimes less, and the gap closes a bit every year. Won't be long until EVs are consistently lighter than the gas equivalent.
It's really not that much heavier, less than double. A Model 3 and a 3 series BMW weigh about the same.
