The point was replacing an existing functional vehicle in 2021. It would benefit from upgrades to electricity production indeed, but it's a slow progression, so holding off until the vehicle is to be decommissioned might be a net positive.
Definitely. There is no sense in upgrading your current vehicle, but it might make sense for your next upgrade (which is my plan, but it might be a decade or so until my current car wears out).
There are other reasons not to go EV, like if you live in an apartment or have to deal with on street parking. That issue will take a long time to sort out.
I believe we agree with eachother.
