Cab owners want the “Taxi of Tomorrow” gone today.

Two groups of cab owners filed suit against the city yesterday in a bid to slam the brakes on the Taxi and Limousine Commission’s plans to replace the fleet with Nissan NV200s starting in late 2013.

The Committee for Taxi Safety and Taxifleet Management LLC suit says the 10-year deal means “Nissan will have a monopoly” and demands a court order to render the deal “null and void.”

The city’s Law Department said “the lawsuit lacks merit.”
