You bring up some good points, but almost nobody in government is thinking economics or efficiency of charger layout. At the Zero Emission Vehicle Infrastructure Plan (ZEVIP) Webinar (each state submits their plan to the Federal Gov't to receive funding) that I participated in for my home state on Friday, most of the bureaucrats seemed primarily interested in the "Justice 40 Initiative" ("at least 40 percent of the overall benefits from Federal investments in climate and clean energy to disadvantaged communities."). They're using public feedback (good), but it's filtered through a point system based on how "disadvantaged" a community is. The end result is that it appears at least 40% of the federal funds are going to be used to install chargers in areas where there's not many EVs.I think you hit on an important point. Queuing theory can easily model how many chargers are needed for any given arrival rate, charge time, and wait queue. The problem is the stations are really expensive and having enough to have small queues waiting for charge at peak times is economically abysmal because they are empty almost all the time. If things stay this way, ultimately I see three paths.
1) Big government subsidies to make long distance EV road trips work for the masses (kinda like how the interstates are paid for)
2) We stick with gas cars for long road trips and/or tolerate really long queues at out of town chargers on holiday weekends
3) The Tesla model is actually right, where buyers pay a big premium for a dedicated charging network.
I wonder if the golden age of electric car travel is actually now. Just (barely) enough chargers and rarely any wait.
