It's a plan to build tens of thousands of charging stations, by 2030.
In all 50 states, with the states and local administrations being responsible for contracting, permiting, buying land, utility work, etc. Most of the work is not on the Feds here.
It should not be at all surprising that 10k+ little building projects take some time to get going. Even from the folks who credulously believed the President could end the Ukraine war in 24 hours.
Oh hang on, I can do better. I have a plan to build 3 billion teleportation machines by 2045. This makes for a great mad libs set.
I have a plan to build thousands of Super Star Destroyers on Exegol by a long time ago.
I think your other comment about it being harder because it's an overly complicated plan doesn't convince me. The complexity and feasibility of a plan are also characteristics of its quality.
But this comment I buy. Color me convinced.
They invented a novel weapon in half the time your heroes dreamed of building a charging station.
