The headline is a bit misleading, as it states that the limousine drivers are "posing" as Uber drivers. The article states that seventy per-cent of the limousine drivers actually are Uber drivers; it is that they are trying to run trips off-application. Still, a figure of thirty per-cent that are not even Uber drivers is high and should be cause for concern.
It used to be that Enforcement here did nothing about unlicenced cab drivers and limousine drivers that took street hails. These days, they will jump a limousine or TNC car that does a street hail quick, fast and in a hurry. In the City and in Arlington (a Virginia suburb) the police will bother a TNC driver who is doing a pick-up, even if he is showing trade dress. That trip had better be on your Uberfone, or the police will impound your car.
The realty is that limo drivers have been doing this for years. The bellhops usually get tipped out to offer rides to familiar drivers that post up outside their hotels. To get around regulation, all it takes is a text message...after all limo service is a predetermined ride at a flat rate agreed upon with both parties.
