I rarely drive a Tesla but on one occasion I arrived at a full supercharger, parked in sight to wait for one to free up and a very angry man charged up to my window stating he was next and dashed away before I'd even comprehended what he said.
His anger was so unnecessary and so disproportionate I was just befuddled. Perhaps if they organised superchargers better a digital queue wouldn't be necessary but as it is at the minute it's definitely needed. Anything to avoid having to deal with angry tesla drivers.
