Twice I have been charging at 500 + MPH, and then along comes a clueless/inconsiderate X and parks in the stall paired with mine. Both times my charging rate immediately plummeted to less than 200 MPH. I then moved over to another stall (we were the only two cars there) and my charging rate goes back up to 500 mph so I know it was not just my car tapering. The first time I was in B and I attributed it to A getting priority over B. But the most recent time I was in A and still lost out to the newcomer. The only other time I shared a charger, it was also an X, I arrived second (all other stalls were full) and I got nothing (less than 100mph) until the other car left. So it does not seem that the newcomer gets priority, or first come first serve. Do S/X just get priority over my 3 at chargers?
