Cleaner air at the expense of what? Electricity isn't free, with the exception of solar. Electrics still have an environmental impact. NiMH of lithium to power a large vehicle? I'm sure companies would jump at the chance to spend an extra couple of hundred thousand for a truck with a lower GVW rating. Plenty of clean burning compressed gas cabs where I live (as opposed to petrol). Gas powered buses too.
Each of us makes choices every day. You choose to ride in the city, you accept the risk. There is no other place in the world like NYC. If you want to live there, you've got to compromise.
