Yes on the system working and you being able to charge. My guess is opposite from everyone else so far, i.e. that it will be a Canadian transaction. If it was the a US transaction just because Tesla is a US company, that would mean that everyone who lives in the rest of the world (outside the US) and supercharging a Tesla would all be paying foreign transaction fees on their credit cards every time they go to supercharge. That's clearly not happening because it would be something we've heard about. Also, I would think a lot of countries would have a problem with the idea that goods/services being sold and provided in their country were being falsely structured as occurring in a different country. I could see them considering that as a tax dodging scheme, depending on the particulars of what taxes are expected to be added to the charging costs.
