Except the electricity to power these cars has to come from somewhere and that often means coal or gas. Then you have the awkward problem is our grid cannot handle a significant number of EVs and no politician wants to talk about who has to pay for those upgrades because they don't lend themselves to cool slogans or photo shoots.
You seem to think that in order to have a viable economy we need to keep polluting the air with fossil fuels. If we all keep on that type of blinders we certainly will have a failing economy. Only so much crap left under the dirt.
