$this->bbcode_second_pass_quote('SpringCreekFarm', '
')I'll have to find that movie to watch again but I'm almost certain that was one of the points someone made in the movie.
What that movie overlooked, and something that EV advocates don't like to bring up, is that there is one critical component in EVs that needs to be periodically replaced, which is
the battery pack. And that thing is the single most expensive component in the entire vehicle, so much so that if you factor in just one round of battery replacement you've probably spent the equivalent of all the oil changes and tuneups in an ICE between when you drove off the show-room and replaced the pack! This was a real problem around the time WKTEC came out because they were talking about nickel metal hydride and nickel is a borderline precious metal these days, but lithium ain't cheap either.
That's why EESTOR was supposed to be such a big deal. Battery lifespan is the single biggest showstopper with EVs. You don't pay as you go. You pay in one huge lump sum every time the pack dies on you, and you have to factor that in for your _true_ cost per mile.
Even with inexpensive lead acid batteries, battery replacement costs shoot the economy of driving to hell. Great if gas goes to $10 or there are outright shortages, but not that great now.
