As an occasional driver of a Nissan Leaf in Puget Sound, the (in my observation) massive uptick in Tesla cars up here has really put a strain on the relatively tiny DC quick-charge network. Where that car can be in and out of a CHAdeMO station in 25-35 minutes, Tesla cars seem to occupy it for two hours. Presumably, and I'm just guessing, this is because a CHAdeMO station is to a Tesla what a 240V level 2 charger is to a Leaf. If I drive to a particular Eastside shopping center, I'd better hope I plan to be there for at least two hours because there's no chance of ever seeing an unoccupied one of the quick chargers there.
Either way, that's why I hope that either Tesla gets its superchargers more widely deployed or that some company takes the hint and builds more DC quick chargers. (Preferably more reliable ones, too, while I'm wishing for ponies. The one at the Lake City Fred Meyer seems to only have two states, occupied or broken.)
