Probably not. What makes Uber/Lyft so compelling is that they can do two things cab companies are legally not allowed to do: (1) subsidize fares with VC money; and (2) cross-subsidize between surge fares and fares during periods of low demand.

From my office in the Watergate, it takes a good 5-7 minutes to call an Uber/Lyft (some GPS/app bug causes people to drive right by and end up on Rock Creek Parkway). If it wasn't $3 to my apartment in Gallery Place, I'd just grab a cab from the cab line.
