The ride-sharing service Lyft
(a cell phone age alternative to taxis) has lost a court battle in St. Louis
to be exempt from that city's taxi regulation.
This should provide some parallels for Little Rock,
where Uber and Lyft are thought to be considering offering service. A judge there rejected arguments that Lyft was somehow a different breed of cat from a car service for hire with a metered charge.
But note that Uber is working to obtain licensing in St. Louis and another service, Carmel, is already fully licensed.
So compliance with codes need not necessarily be a bar to phone-dispatched ride services.
