I encountered this today. Went to try my new Lectron adapter and realized the alignment wouldn't allow me to charge without taking up two stalls. There was line of Teslas waiting to charge so I couldn't do that in good conscience so just left. I'm assuming doing this would be considered pretty poor etiquette.
Yes, it sucks. You have to be on an end unit to the right, and up tight against the curb. Or you have to be rude and take up 1.5 spots. I even looked on Tesla's website, and they SHOW that, as if that's a reasonable approach. They need to simply have an extension available.
I went on my first 350 mile journey, thinking I could use ANY tesla supercharging station. NOPE. They limit which ones you can use. If you added the car to the App, if it doesn't show up, you can't use it, even if you know where it is.
I drove to one that I knew was there (because I had had a model 3), and it was ENTIRELY open (all 12 stalls). But I couldn't use it. Tesla is limiting access to non-Teslas, and what is so stupid for them is tht they aren't getting any return on those stations if not in use. That is the dumbest business model I have ever heard of. They know if a car is a Tesla or not, so they should just determine when, say 75% of the stalls are being used, then they disable so only Teslas can use the others. I get them wanting to prioritize Tesla owners, but it's horrible.
The only Tesla ones I could use were either slow charge, or so far off my route it was ridiculous.
So I wound up using ElectrifyAmerica and SmartCharge systems. They worked once I "figured it out" with their apps (not trivial).
And in the winter, the prologue only gets about 250 miles/full charge! And it takes about an hours to charge from 80% - 100%. (Took about 30 minutes from 10% - 80%) on a 150kW charging station.
Problem was waiting the 15 minutes for a slot to open, and cost was around $0.60.kWH. That comes to $6 almost when you are only getting about 2.3 - 2.4miles/kWh. I am hoping in the spring/summer that climbs back up to 3+.
Fortunately, I do have an L2 charger at home, so it's cheap to charge, and convenient of course.
I probably won't be taking my Prologue for journeys more than 200 miles round trip for the time, and just use my wife's CRV hybrid, until the infrastructure improves over the coming years to make it easier to fast charge on major highways, which should also drive down the price per kwh as competition ignites.
