Agree with this. When someone sees charging availability in their area they start thinking that an EV might work for them.As with everywhere i have been there is deep concentration fo Tesla to be found the nearer one is to a store.
Everyone who says there si saturation really does not understand how important stores are. California, Beijing...everywhere. Superchargers and stores are the crucial factors. Service Centers and Service vehicles can be major sales aides too. It's not so much awareness as it is availability.
When they are ready to buy they also want to know that servicing is available before pulling the trigger.
So it's true that Tesla has big untapped markets in many parts of the country.
