I am all about the electric car.......................but here is the thing...
They are going about it all wrong.............By that I mean that the work trucks and such should have been the first thing to change.
Typically, work truck and delivery truck are driven within the 300-350 miles range of currect EVs. They may be able to go a little longer due to the the increased carrying capacity of a 3\4 ton or above truck. Also, these type of trucks are usually owned by companies that are within an urban or commercial area where 3 phase power is normally available, making it easier for 480 volt charging to be done, and easier on the grid.
If they would have done that, and used work trucks for the guinea pig.........then figure out battery tech in real time, got public trust in the EVs, allowed the grid to catch up slowly, etc............
