Last month we told you about NY cabbies who were disgruntled about the new requirement that all taxis have GPS and touchscreen monitors that allow customers to pay by credit card. Yesterday began a two day strike that showed that the drivers were serious in their threats about suffering a lack of privacy with the new rule. Backed by The New York Taxi Workers Alliance, it wasn’t apparent how many took part in the strike and the ramifications of the opposition remain to be seen since other groups opposed the strike.
