Most people who use short stay are there picking up people, since you can’t pick up from the terminal forecourts anymore. They are there for about an hour, sometimes more, and they might well need that bay. You’re forgetting that not everyone drives a Tesla. The Nissan Leaf I had on loan for while would struggle to do 100 miles on a charge. Less when it was cold and raining. So that 28 miles of additional range, or half that on a cold winters night, is the difference between getting home, or not...
The fact remains that hogging a charger for your own convenience, when ‘there are superchargers a mile down the road” that you could use when you get back, is plain, unadulterated selfishness. It matters not what you consider the intention of the chargers is, it matters that you are denying the use of them to everyone else when you don’t need them.
Put the shoe on the other foot. How would you feel when you arrive back from your trip to find the dreaded vampire drain has eaten into your range so that the nearest supercharger is just beyond your reach. The chargers that are within range are filled with the 100% charged EV’s whose owners have buggered off for a weeks skiing. They didn’t think your need was as important as their convenience, and besides, what are you going to do about it? Wait for them to get back?
We are at a crunch point in EV ownership. The already stretched and oversubscribed infrastructure supporting them is going to have to accommodate a number of EV’s that is expanding faster than the infrastructure can keep up. If you’re not charging, you need to get out of the way so someone else can...
I can’t believe that such simple consideration for others is even a matter for debate. It’s wrong, and no amount of guesswork at the usage, load factors, the reasons for installation or the motives of others who might or might not use them makes the hogging of a charger for three entire days ‘right’, ‘ok’, or even remotely justifiable. It’s the act of a complete arsehole, so please, don’t do it.
