That doesn't seem to be a problem for the competition. Prices are the problem, and Uber is trying really hard to lower the prices and profit, that's why the algorithm IS most important.

It is. I get an uber where I live within 2-3 minutes. And sometimes I've gotten uberPool matches essentially going to the same destination picked up within a block. These are only achievable with considerable penetration into a local market.
