This person has made the common mistake of thinking &quot;Uber for x&quot; means &quot;an app for finding x on a map.&quot;<p>OP: the innovation of Uber has nothing to do with their car-finder app.  It has to do with the fact that they&#x27;ve figured out a way to compete with a huge established business that historically has required huge capital expenditures to build a fleet of cars, and they&#x27;ve done it by tapping a massively underutilized and very cheap resource: other people&#x27;s idle cars.  This is precisely why taxi companies can&#x27;t respond just by building a great app for hailing a taxi.
