Under ideal carefully controlled situations it may well work like that,in real world scenario's I doubt that 250 miles and a full charge in ten minutes is likely to be the norm.

Not to mention when the batteries start to develop "memory"

I also doubt that it would suit "most" americans,things are fairly spread out where I am and I regularly travel several hundred miles,where exactly would I plug in while out and around?

Where would most people do this? I know I am not alone in traveling long distances.

I'm thinking there's probably another variable you're overlooking,it can't be cheap to charge an EV,especially as often as it would need to be done,it certianly wouldn't be cheap once the time comes to switch batteries out.

The battery type doesn't develop memory, it does wear out.2000 cycles are given specs by BYD (a cycle means a recharge of 80%, or 2 40% recharges contrary to the belief by some people that each charge, no matter how small, counts as full cycle). So if you drive 400 Miles a day, needing 2 reacharges you would drive 400 000 before needing a new battery. Even half as much would be around the lifetime of an IC engine.

The TCOs aren't the problem, but making them clear to everyone.

I took the numbers of a German Automobile Agency once, for 4 years and 10000 miles the depreciation only was 40% of the cost of cheap cars and 60% of the luxury ones. The remaining costs are all affected by going electric.

The network of charging stations would exactly be where the most work needs to be done which could be done at the same time the power grid gets overhauled. Thats why it is not a walk in a park but a project comparable to the space program in the 60s.

Edit: I too think however, that non-plug in hybrids are inefficent and only serve as smug mobiles.
