60,000 square feet is interestingly the size of a small warehousing or distribution center. Your average Costco for comparison is well over 100,000 square feet. I suspect such facilities will offer mega-chargers for drivers to top up before heading off to wherever they are going. Especially if the facility is part of or does a lot of business with someone who has a fleet of trucks (say UPS).
We'll also likely see a lot of charging stations at the rail and port container yards (which are notorious for long waits for truckers) and possibly CFS stations.
