Great, we can all agree on this Internet forum that charging at a supercharger to avoid paying a higher electrical bill is wrong. Hooray for us, but tesla is selling this car to the common public, not just us. The common public is used to filling up at stations frequently anyway. This will happen quite frequently (and already does at a lot of locations, like Folsom). I understand it can be frustrating for some, but realistically those who are filling up 40 miles won't be there any longer than a gas pump, and it won't add much to their daily commute either.
quite frankly, while I don't know if I will switch to this method when vacaville opens up (probably a moot point because I'll likely move to the Roseville area soon in the next six weeks.... But when that one opens up....), I think it is a really easy thing to do.
in my current situation, I would drive to and from work daily for about a whole work week (I use about 30 miles a day), and then once a week I would get dinner over by the superchargers which will be on may way home if I go a slightly longer route.... I have wasted zero time as I had to eat anyway. It would save me 100 or maybe even 200 dollars a month, and it wouldn't inconvenience me at all. My car would only be there once a week for an hour, so it wouldn't really be too disruptive, and it would take one out of 8 stalls for an hour. I would be using .07% of the available supercharging ability of the station, and I wouldn't feel guilty.
while I don't really plan on doing that, I really don't see it as a big deal in most places. It really would be more hindering when this is employed by people who use that whole range daily, but I can't blame them either, because they are likely paying $25 a day in electricity. That's $500 a month, which is huge. Those same people were likely paying $600 a month or more for gas for the same driving in an ice. Now by switching to a model s, they can save nearly enough to pay the monthly payment on an s60.
no point fighting it, because as there are more on the road, this will happen frequently.
tesla put the superchargers out there to enable road trips, but not solely for road trips.
