I did not see this issue addressed in the FAQ https://www.tesla.com/support/supercharging . My aunt & uncle are considering buying a Tesla, but they live in a condo where they can't install their own charger. A new Urban Supercharger opened up a few miles from where they live. As I was discussing things with them, I made sure to mention the Supercharger idle fees.
I fully understand and appreciate the idle fees and 50% occupancy rule for normal Superchargers. When the power is shared between a pair of pedestals, the location is at 50% occupancy, and you've completed charging, then you could be blocking somebody else from charging at a faster rate.
But each Urban Supercharger has its own non-shared power. Therefore, as long as there is an open pedestal, you aren't preventing anybody from charging or from charging at a higher rate.
Do the idle fees still apply at an Urban Supercharger when it has 50% occupancy? If so, why? Wouldn't it be more logical to only apply them when they are all occupied, or maybe if only one pedestal is available? Obviously we should encourage people to move their vehicles when they've completed charging, but IMHO, the penalty should only apply when you're preventing somebody else from charging or from charging at a higher rate.
I haven't used an Urban Supercharger yet. Can anybody confirm how idle fees work at them? Any other constructive thoughts or criticisms?
