The city of Boston, Massachusetts has become the first city in America to officially approve of Ford's Transit Connect (2010 North American Truck of the Year) as a taxi.
Mark Cohen, Boston PD Licensing Division director, says this about the Transit Connect: "It's the closest thing to a purpose-built vehicle for taxi use that I've seen in 25 years." I guess he's never been to the UK...
For many places, the issue with replacing the large, Panther-based Crown Victorias has been the regulation of vehicles that are allowed to perform taxi duties. A successor would have to meet various size/measurement/cargo/safety standards before approval, and the city of Boston has deemed the TC Taxi worthy of the job.
