CHG-ON
Still in love after all these miles
I paid to enable supercharging on my 9-14 P85+. I totally get the OP's point. But I didn't do it thinking that I would either save money over gas or even break even. I did it to have the functionality. And I will say, it has proved priceless. While 95% of my charging is at home, there are places that I could not get to without a supercharger. Or, I would have to wait for a ridiculous amount of time at a L2 charger, which would make my trips untenable. So I paid for the incredible convenience. I must say, plugging in for 30 minutes while I grocery shop before visiting family and coming out to a charged up car is about as good as it gets.
I would be totally fine with a per kw charge over paying up front. I am sure I would end up spending less. But it wasn't an option then and still is not. It will be very interesting to see how this goes. It's still much cheaper to pay for electricity than gas. But I wonder about the psychological impact of knowing that one would be billed whenever they use it. It might cut down on locals taking advantage of the "free" charging they now have, thus freeing up slots. Though I have yet to see any valid data on how much of a problem this might be.
