While traveling last week, I noticed a weird situation at the Brentwood (TN, near Nashville) supercharger - I wonder if anyone else noticed this, and/or if it is going on at other locations also. The Brentwood SC is in front of a Tesla showroom; there is a bank of 6 charging stations. It appears to me that the Tesla people are keeping inventory cars parked in 4 of the 6 stations, and blocking one of the remaining open ones with a cone, thus leaving a single charging point. (I think they are inventory cars because they have dealer plates or no plates). There is also a sign saying Tesla maximum charging time 40 minutes. I have a couple of issues with this (assuming my impressions are correct)... first, if you are traveling north on I-65, the next SC is in Louisville. My Model S tells me it needs an hour and 10 minutes to put on enough charge to get to the next SC on the route (it is very cold and cabin heater is needed). What am I supposed to do? Second, is Tesla creating an artificial charger shortage by parking inventory vehicles in most of the SC slots? Are they trying to generate charging revenue? I noticed (when I charged for more than 40 minutes because I had to), that it took a long time for the charging cable to release from my car when I tried to remove it; I gather that it is sending data to the home office so that they can charge me $1 per minute over the 40 min. limit. Now, to be fair, there are a couple of factors - number one, the Tesla showroom lot is overflowing with Tesla cars - maybe they really do need the parking; but leaving a car in a charging slot when it doesn't need charge violates the first principle of EV etiquette. Second, there is an EVgo CHAdeMO charger a couple of miles away, which works (assuming you have the CHAdeMO adapter) - but it is slower than an SC and kinda pricey (I think $4.95 to connect plus 20 cents per minute - but these fees might have changed) - still more expensive than overages at the SC. Either way, the situation seems weird. I expect to have to pay some charging fees at my next service. Has anyone else noticed this going on? Or am I completely off base here?
