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.
