Doesn't solve the issue of how electricity gets to those charging stations. Specially when there will be dozens of them in that big parking lot.
Grid basically works with electricity being produced in large plant, then it's voltage is raised for long distance transmission, at other end it is lowered in stages. And all of these stages have limited capacity of how much electricity can pass through them. And there isn't too much extra in these as that would cost more. So it's a big thing to build up...
True, but any consolidation helps the 'last x' problem, generally. Instead of worrying if every house can charge at once, you only have to worry about the shopping centers. It doesn't help at the power station level though of course.
