It's not bullshit at all. It is a lot better for cars that are being used to not shoot out smoke from combusting refined oil. There will always be cars in use, so it will always be better for them to not shoot out smoke.
It's not possible for all workers to live inside dense cities and use public transport and work in offices or at home. MANY other jobs are out there and still need doing every day. Everyone who physically maintains all of our critical infrastructure, manufacturing, and food supply industries is pretty much going to commute to work one way or another. Millions of those people don't live in cities with public transport and/or don't work where public transport can take them to. EVs are an improvement for all of those necessary use cases, because the vehicles they need could not be shooting out smoke.
