1) Their app 2) The reliability of getting car with them vs. waiting for a cab. 3) Their vehicles are much, much, much nicer than cabs in my area. 4) The purchase experience.
Have you ever asked yourself how they do that? It's not like taxi drivers are fabulously wealthy.
Like you said, cab drivers (and probably cab company owners) aren't exactly fatcats. Meanwhile what's Travis Kalanick's net worth? How much are they paying top engineers at Uber?
Don't get me wrong, there's definitely corruption and protectionism in the existing taxi industry, but I fail to see how the low $5-7 fares are anywhere near sustainable. Is the revenue from surge pricing enough to offset the current discount?
Aren't cab drivers in major cities dealing with the purchase or lease of million dollar cab medallions? I believe that could factor into higher prices for consumers.
They don't even always have a price advantage anymore, especially if there's a surge. I needed a cab from Chicago Midway to my hotel last night, Uber's upfront price was $48 (and an eight minute wait), a regular taxi was $40 (including 15% tip) and no wait. I took the latter.
