SAN FRANCISCO Spend any time in San Francisco, and you’re bound to see a lot of cars drive by that have pink mustaches stuck to the front. They are the face of new "ridesharing" services that are muscling in on entrenched, and heavily regulated, taxi and limousine companies in San Francisco and other cities.
Drivers and passengers use mobile apps to find each other. By crafting the bargain as a ridesharing service where any payments are voluntary, the app providers skirt many of the requirements governing taxi and limousine companies.
