They are only going to open select Supercharger sites. i.e. ones that have low utilization. Most likely only V3 sites.They better take care of the older 150kW 6-8 charger spots, which there are plenty of. Tesla needs to quadruple those and make them faster as well. I am not looking forward to waiting in lane with Leaf, Kia or whatever else there is.
Those who supercharge often on trips should know what I am talking about.
Also, you won't be sharing chargers with a Leaf, as they can't use CCS, and Tesla isn't going to be supporting CHAdeMO. Now sharing with a Bolt will be bad, they charge so slow...
