Tesla’s a dick for opening charging up to other brands without making the cord long enough, but without extenuating circumstances it’s a dick move to take up two spaces to charge (I don’t consider “I don’t want to drive 10 minutes down the road” an extenuating circumstance). It’s not something I would do and it’s not something I would expect the lot owner to just put up with if it was them telling me to move it.
Again, I want to emphasize the Tesla guy calling 911 is unhinged. That doesn’t mean other parties can’t also be behaving in a sub-ideal way.
