> Uber proper is priced for people who are used to driving their BMWs or hiring limousines but don't want to this time.

I've taken a few black cars not because I'm into limousines that much, but because of airport regulations, and the ride is typically within the range of the cab. Cab drivers in the US also expect to be tipped in 10-20% range, which leaves Uber black car service frequently a winner price-wise.
