People need to shut up about opportunity cost.

It’s theoretical, not guaranteed which the vast majority are too busy living paycheck to paycheck to even have.

Let’s be honest, you aren’t going to invest that 10k unless it’s already invested and you’ll be getting closer to 5%. A lot of ifs.

You can seriously do the math yourself.

Get quotes on the insurance, estimated electrical costs from your EVs customer reported efficiency and your utility rate.

Compare that to your ICE car of choice.

Decide for yourself.

Charge it to 90% before you go and it’ll be fine.

If there are better batteries then I’m sure someone will be offering battery upgrades on the older EVs.
