I suggest Nissan consider building some stations between Hermosillo, Sonora, Mexico and Tucson, AZ, USA. One rationale is that Hermosillo does now seem to have a Leaf-oriented Nissan dealership and a little bit of charge infrastructure. Also: there is a lot of construction going on Mexico route 15 between Hermosillo and Nogales, AZ, USA. It might be a good time to negotiate to include some public EVSE. There is also a Nissan dealership in Nogales, Sonora, Mexico which I think eventually should be certified as a leaf dealer, and so why not do this sooner rather than later (especially with Nogales, Sonora having so many potential drivers).
plugshare.com can give an idea of the route, and what is already there along this route:https://www.plugshare.com/
This route is one that people travel for pleasure (visiting the beaches) and for business. I don't really know if it will be profitable in the near-term to put stations up, but I do think it could be worthwhile to sell Leafs in Nogales, Sonora and then to explore the question of building out dc quick charging from these Leaf cities.
As I understand it, in general Nissan has a very strong presence in Mexico.
