They are not even close to feasible for everyone to use them. The power grid is not even 20% the way there.
They won't be what we drive in the future. Likely hydrogen, perhaps nuclear.
Some people say things like electric vehicles aren't feasible. In addition to all the EVs that have been on the road for years, we now have electric powered ships that can cross the ocean to add to the evidence that their theory isn't looking so hot.

Hydrogen/ammonia for ships and possibly aircraft
Nuclear to power nearly all base level production including powering H2/Ammonia production as it is most dense energy source I know of
Battery electric fantastic for short range like cars and bikes and tractors etc, or also hydrogen fuel cell if developed and adopted like BEVs.
Anyway the future is bright and abundant with reliable accessible energy
Let's keep building 💪
