The incentive is built into the time cost of supercharging. Charging is relatively cheap (compared to gas). Folks that can charge at home almost certainly will purely for the convenience of it. If someone is so hard up for money they're willing to drive to an SC site and wait, then I'm not going to begrudge that.
Indeed. I think, as usual, folks are looking for trouble. And making assumptions like when they go to a supercharger, (a) all slots will be full and (b) it'll be those darned uppity locals. There's no network yet and already the grumbling begins. ;-) The times a local might charge and the time a passer-through might charge won't necessarily coincide. And if they do occasionally, well, who's that different from having to wait on anything else while you travel (gas, rush hour traffic jams, accidents, etc.). I'm more optimistic.
The time cost is an excellent point. I was already thinking I wouldn't go out of my way, but might stop off to fill up if it's on my way to/from somewhere I'm going anyway. But really with the time cost, especially since topping off would be the slowest part (the last 20%, probably) . . . I'm not sure even that would make much sense. Maybe if I had a long trip later that day and was nearby (but then I'd be a traveller,
local or not, darnitall). Time is money, etc.
Also I wonder if folks believe the supercharger expansion plan will stop cold at 5 years. I suspect not, at least not if Tesla does as well as we all (hopefully) hope. The network would grow more, existing stations may add spots/capacity (or move to larger lots and add more spots), etc. And then there are other charging options that will increase/multiply as other EVs take off, some companies have charging spots for employees, etc. Etc. etc. etc. I just don't see this being a major issue.
But I'm rambling and none of us has a crystal ball anyway. ;-)

P.S. Another thing to consider is that the supercharger stations most likely to be busy . . . aren't they likely to be near urban areas . . . likely to be popular destinations and/or stop-n-charge spots for travelers? It seems like the horrid out-of-towners will be the true threat to supercharging nirvana. :biggrin: :wink:
I'm teasing a little, of course, but it does seem quite possible.
