In New York City, a significant number of taxi drivers have gone on a 48-hour strike to protest (in part) mandated GPS in their cabs (the NYC Taxi & Limousine Commission will track and log vehicle activity).
Aside from the backlash itself being noteworthy, most AVL-type systems that I’m aware of track organizations’ own vehicles/assets. The TLC is the agency responsible for licensing and regulating, which makes this scenario a bit different, does it not?
GPS Systems are becoming daily – it is just unbelievable precisely what tech are able to achieve now!
