assuming you live close to one of these (or are passing by it on a long route), it's fantastic!!
...but take my boss, for example, who is still considering a Model S until the MB S-Class cabrio comes out. He doesn't care that the car will depreciate and he'll lose huge on it. Money is not an object to him. He likes the Model S, but even 30 mins is too long for his snobbery. He would much sooner pay for his own charging station at home than drive to a parking lot for 30+mins. IF, however, they put in an owner's lounge, with free wifi (so you can work there, for example) or for-fee niceties (like in any AMEX lounge), his snobby as$ would happily go and get a free charge.
...having the 'free' electricity helps those who are trying to make a sound economical investment in transportation. Selling $80k+ cars with the ability to get free transportation ignores that those with this kind of money won't sit for 30 mins+ while their cars charge.
Superchargers are best for opening up the ability for long-distance trips, but certain planning could get them to be used and profitable by the rich.
With that being said, when the 'budget' Teslas come out, having these supercharging stations will be brilliant for regular users - but 8 bays won't be sufficient. Hopefully there is room for expansion.
If the above sounds negative, I don't mean for it to - it's constructive criticism and I applaud every effort made to bring BEV back to the market.
