As a non-Tesla EV owner, I would happily pay surcharges for charging on Tesla's network if it meant I could reliably use my vehicle on extended trips out of town. Tesla charging network has a very good reputation for reliability, which is a primary concern if I'm traveling on the highway. It's not something I do often, so paying a premium once in a while to use my EV instead of my ICE vehicle seems like a decent tradeoff.
Ugh, please don't take this stance.
Gas stations don't charge different amounts for gas depending on the type of car, and EV charging stations shouldn't be permitted to do so either.
I don't have an EV, but I agree that Tesla has a much much better reputation for reliable, working charging stations in the US. If people will actually pay more for that experience, then sure, Tesla can charge more than a competing charging company. But they should be required to charge the same amount regardless of vehicle.
The only exception to that, I think, is that they should be able to charge differently based on charging speed, which is related to the type of vehicl. All gas cars will fill up at more or less the same rate, but with EVs it depends on the battery technology and the car's electrical system. Taking up space at a charging station for a longer amount of time to consume the same amount of energy is a cost to the operator (and an annoyance for anyone waiting in line), and it seems reasonable to charge for that. So I think it would be fair to charge $X/kWh + $Y/min.
