A trade body representing more than 8,000 New York taxi drivers is threatening to call a strike over the city's plans to introduce satellite positioning systems in every yellow cab.
Bhairavi Desai, executive director of the New York Taxi Workers Alliance, told AFP Wednesday that drivers considered the proposals put forward by the city's Taxi and Limousine Commission (TLC) infringed on their rights.
"Taxi drivers sometimes use the cars in their private time. Why should they tell the TLC where they are going on a Sunday with their family? This is an invasion of privacy," she said.
"We are ready to go on strike at no notice in September if the TLC doesn't cancel its plans to install a GPS in each vehicle," she added. The alliance represents some 8,400 of New York's 26,000 taxi drivers.
Under current proposals, the city's distinctive yellow cabs will from October 1 have to be equipped with the new GPS system, which also includes a monitor for passengers to follow their route and check news and weather.
The system also allows bank card payments.
According to taxi drivers' groups, the devices cost more than 5,000 dollars to install and will inform the Taxi and Limousine Commission where they are, how many trips they have taken and how much they took in fares.
