TAMPA (AP) — A simmering feud between the agency that regulates cab and limousine services in Hillsborough County and a handful of upstart ride-sharing companies has escalated after a Lyft driver refused to take a plea on a misdemeanor of driving a taxi without a license and demanded a jury trial.

The Tampa Tribune reports there have been nearly two dozen cases made by local transportation inspectors over the past two weeks.

The county's Public Transportation Commission, which has been locked in a dispute with Uber and Lyft over what level of regulation the ride-sharing services should be subject to, set up an operation to cite the drivers.

The charges come at a time the companies are trying to negotiate terms with the transportation commission under which they can legally operate.
