auto emissions aren't just fuel reaction byproducts. you know when your tires and brakes wear down? where do you think that mass goes? its a very wasteful form of transit, and moving tons of steel and lithium for every 1-3 hundred pounds of person is insane. bare bones ICE augmented bikes would be a greener solution than electric cars. if we switched all our infrastructure to electric cars, wed need more sodium and lithium than exists on earth and a nuclear power plant for every truck stop, complete with waste-heat outlets and and radioactive waste disposal.

electric trains running overhead wire from green or glowy energy sources and ebikes/scooters or walking to cover last mile is of course ideal, the economy of scale and efficiency of form from trains and barges and reducing excess mass moved from using escooters and ebikes for last mile trips may actually keep industrial society viable.

sorry, but under capitalism you can't use stopgap measures. natural gas was a harm reduction measure, now natural gas profits and lobbies are a barrier to green energy and electrification.
