That would be interesting... The map in the Teslas already does this. It plans the trip, tells you when/where to stop, will tell you how many of the charging spots are currently occupied. Wait times aren't there, of course, but likely will be as more charging stations are built out. The expectation that the entire infrastructure be mature before any cars arrive is unrealistic- no industry ever has done this (were there a million gas stations and an interstate system in place in 1908 when the Model T arrived?). The better question is why aren't any of the other manufacturers making any real effort at all at fast charging? Even if Tesla goes away, the 10,000 existing Superchargers don't, and by the time they would actually go away, that number will be 20k+. Perhaps Buffett will come in and swoop them up.
