Assuming that there are some (6 here) 30-minute general parking spaces,
it would have been better to power all of these with the "B" arches, so
that even when all the "30-min" spaces were ICEd, all of the "paired" ("A")
Charging-Only spaces would have the full SC charging current available.
That is a really good idea.
Even if they did not do that in the case, it's probably still worth suggesting to Tesla for future sites.
