A taxi drivers' group in New York has set a strike date next month to protest new rules requiring all cabs to have electronic equipment including GPS and credit card systems. Other drivers' groups say they will oppose a strike. The New York Taxi Workers Alliance, which counts more than 8,400 members, will call for drivers to idle their cabs Sept. 5-6 to protest a requirement that all cabs have Global Positioning System technology, executive director Bhairavi Desai said Thursday. The group fears the device could be used to track drivers' movements. The alliance also has expressed concern about fees drivers would pay for credit card processing. "We are ready, willing and able to walk out," she said.
