After getting my TLC license two summers ago, I’ve since adopted “rideshare driving” (which is basically giving out rides in a black car vs. a yellow cab) in New York City (NYC). It’s become my main source of income, and hence I’m doing it full-time (40+ hours per week). And depend completely upon the income I make doing “rideshare driving” to pay bills, pay down debt, and otherwise live.
It’s not abnormal for “rideshare drivers” in NYC to be driving full-time, because often the drivers have big overhead costs that are unique to this location. For example, you can’t just use any old car for ridesharing in NYC. The black car has to be registered with Taxi & Limousine Commission (TLC), which requires an inspection, commercial insurance, etc.
