Nice sound bite, but Driving a Lupo-like vehicle getting 60+ MPG on gasoline or diesel would have to have had a positive effect on emissions, not to mention particulates and highway damage.
I think EVs can have a beneficial effect on climate change, but we're doing it all wrong. Manufacturers should build, and Americans should buy, small, shorter range EVs for suburban and city use. For the battery capacity of one Mercedes EQE you could build 4 Honda-es. And it would work better than the Mercedes for the vast majority of people's transportation needs. Keep a larger ICE car for trips, or rent one. Or take a train.
