EVs don't have direct emissions. Thank goodness a study showed that. They also tend to be cheaper to drive over time, once purchased, electricity costs are usually a lot lower than a tank fill up thanks to the difference in cost and the efficiency of EVs. Now we have a study from MIT showing what everyone has been saying all this time is true.
Now what?
The government should push hard on regulation to provide an infrastructure support for EVs, such as charging areas everywhere, including apartment dwellings and common retail areas. Make them solar assisted. They should run regular buy back programs to incentivize trading in older ICE cars. Any public service using vehicles should be transitioned to EVs - buses, mail, trash collection. Anything that does a lot of local stop and start movement, which is where EVs excel at their efficiency and emissions reduction vs. ICE. And while we're using the government to improve EV conversion, how about also improve public transport (which should be all EV) to reduce the car count on the road even more.
Like everything else, we should have been doing this decades ago, as this isn't news to anyone. Hopefully this still has enough of a positive spin for this forum.
