It's still pricey to convert a car to electric but people are doing it via clubs or self interest on their own for a few thousand.
IMO, you'll see mechanics or shops offering to convert your car to electric for a couple thousand bucks. Probably not people's vans or SUV's for long trips though! LOL!
Are there any public companies that offer such a service yet? LOL!
My guess is that the big car companies are ready to roll out all electric vehicles.
