Fully agree with your article. I think you should add something about moving heavy cargo by truck as well. Not all the particulates from these big rigs come from the diesel engine, though the black clouds at stop lights are annoying when I ride my bike. The Greenland ice sheet albedo problem is mostly caused by particulates from tires, though forest fires may have passed them now. Feedback loops. The problem is the car overall. I have 10,000 miles on my bike tires and they show almost no sign of wear. If we can get the cars and trucks off the roads, at least in part, a lot more people would ride, instead of just crazy people like me.
