You start by saying US2 is getting supercharged in 2020. Then you list a bunch of supercharger locations (some already open and some in construction or permit stage) that may be tangentally along US2 but were put in place to serve various interstates and other purposes. I have seen no evidence that US2 travel will be enabled by superchargers any time soon. If you have evidence, please provide it.
I also only see US2 locations being used as a drop down from major cities in Canada or the TCH. While I would love the Highline to be fully charged, I don't see it in the cards anytime soon. Would like to see 94 finished, and a couple other spots.
