MJS73 beat me to it. It's easy to claim a certain range, but then there's real life.
In theory we could use an EV with a (claimed) range of 350 miles to make a Costco trip. In reality we'd never make it back home, partially due to speed, and also because of having to deal with altitude changes.
So plug it in at Costco then, you say? Well, they don't have any chargers. We could go to the Porsche dealer, which isn't far, plug in there, and go to Costco in a loaner. In theory.
Okay, in real life, too, but it wouldn't be fair to the dealer.
