At my office there are 8 tesla destination chargers on underground level 1, paid parking. Unfortunately they were located in spots closest to the elevator enterence. Before Tesla charger installation, those sports were marked hybrid/EV only, and was filled with ICE cars 98% of the time by 10am. After Tesla charger installation, there was no change and you have to arrive before 9am to get a charge. They recently put up some more obvious Tesla only signs and it got better, ice is now uncommon and other hybrid/EV occasionally park there. You can almost always get a spot as there are less than 8 Tesla in the building.
Propeery owners should always locate chargers on the least desirable spots.
