If BYD and others will be offering a 5 minute charge then range is almost irrelevant. Cost of fast charging will then become almost the sole issue.
I can't imagine myself ever needing a charge that quick. On a long drive, I would have traditionally stopped to take a break and possibly fill up (although I'd usually drive to a nearby supermarket) so there was the time for me doing what I need to do (stretch, make a call/check phone, toilet stop, a bite to eat) and THEN going to the petrol station to fill up.
Now I can let the car 'fill up' while I'm doing the other things, so for me it's quicker than when I had an ICE car.
I really don't need a 5 minute 1mW charge, and I expect those that might will probably be in a position to swap driver to do a far longer trip - although surely one or more vehicle occupants still need to stop occasionally to do something that takes longer than 5 minutes.
