I think they should favour jurisdictions whose policies promote EVs. And that is also in their financial best interest as those jurisdictions will sell more Teslas and therefore use SCs more which will provide more revenue for Tesla, since those of us who SuperCharge for free will soon be an endangered species. But I guess you can argue that it is a chicken-egg situation. As I show in the graph below even if you adjust for population size all of the EVs sold in Canada have been in QC, ON and BC. When you don't adjust for population it is even more skewed (these are all EVs, not just Tesla)
