The continued saga of parking and SpCs and charging and....
...my take on this is that TM made a strategic mistake at the beginning, although it is not too late to correct. ALL the signs should use only the word "charging" rather than having any mention of "parking". That would create, reinforce, imbue into all - not just Tesla owners and not just ICE drivers - that these slots really and truly are analogous to fuel station spots: they are NOT meant as parking sites.
Thus, we would have signs like "30 Minute Charging Only", "General Charging Only", "Tesla Charging Only" and so forth. AND...would probably (am sure this depends on locality-by-locality ordinances, though) avoid the need for TM to relegate some of those valuable 6 or 8 or so slots to handicap only - as, again, these are not parking spaces.
