Our complex added shared EV spots about six months ago and it's turned into a mess in a few different ways at once: people not reserving spots so it's first-come-or-nothing, someone leaving their car plugged in for hours after it's already done charging, and arguments over whether unplugging someone else's car to free up the outlet is ever okay. Management hasn't put any actual rules in place yet. What's actually worked for people dealing with the same problems in their own buildings, not just what a policy document says should work?
