The Uber market cap is explained by a bet on worldwide autonomous taxis, though I think Tesla is better placed to take that market, again it anticipates future success.

It's tough though: most people don't care about car based internet when their phone already has it.
It doesn't feel like anyone has yet found a recurring revenue stream for vehicles that has met any actual demand.
The Tesla connectivity is really part of the whole car experience and I would probably be willing to pay quite a bit more, I was surprised by how reasonable the price was.
At least Tesla is a real thing.
Also, get your facts straight. Citysearch and Zip2 are not the same company.
