Ridesharing in Boston and Washington, D.C. suffers from one-way streets and riders who call at the end of a dead-end street rather than walk 50 meters to a main street. Uber and Lyft suggest walking short distances to be picked up under certain conditions described below.
Uber Pool Express
Uber Pool Express requires walk-to-pickup (and walk at dropoff) in specific neighborhoods in Boston.
Even regular non-shared Lyft asks if you’d like to walk to a better pickup spot in Washington, D.C.
Previously, Uber Pool would suggest better pickup spots, but they were optional.
The Boston Uber Pool mandatory walk to pickup spot neighborhoods are: Back Bay, Fenway and Harvard Square. Other neighborhoods also need this feature, so Uber must have used some demographic/statistical measure to pick on these three neighborhoods first.
In these zones, you will be asked to walk up to 250 meters (1/6 mile)–roughly like Commonwealth Ave. to Boylston St. in Back Bay, but more commonly like one east-west block in the Back Bay area.
