I've never had a problem in Inverness to be honest, other than last time the car dropped its charge while I was eating my cheese and onion omlette, without me realising, then I had to run back and reconnect it. I was worried I might get an overstay penalty but I didn't see an excessive debit from Tesla so somehow it worked out OK. Six is 50% more than four. I think there are only six in Fort William too, but I've always got one there. Even last time when two cars were charging on the wrong side and so blocking four bays. (Couldn't they at least have charged next to each other so only blocked one additional bay?)
