Isn't it? Because the dictionary says: "a task or activity that has no hope of success."
So let me double down: rushing to electric cars without having the capacity/infrastructure (and without the feasibility to have it even for decades) is a fool's errand.
It would be more of a fools errand to try and halt (or slow) the inevitable world-wide transition to electric cars.
Japan were world leaders in electric drive trains with hybrids like the Prius. A perfect way to gracefully transition from ICE to all electric. This was almost 35 years ago (1997). But they squandered that lead by focussing on the dead end technology of hydrogen.
