Others hide out with their marking taken off (in defiance of section 3.4 of the TNC Pilot Program) at deserted terminals and corners of the airport with their phones ready to accept rides.
Still others continually circle both drop-off and pick-up areas looking for rides with their apps open.
They are both a major cause of congestion and blockers of curbs –making it difficult for cabs, legal limos and the general public to drop off and pick up their customers or friends.
These poorly insured, uninspected vehicles with their unvetted and untrained drivers are the ones that are causing the congestion at SFO: not the vetted, trained and experienced drivers of fully insured taxicabs that have been inspected by the San Francisco Airport itself.
The TNCs remain the only form of mass transportation that trick their customers into signing a hidden waiver of liability in case of negligence before allowing them to ride.
At today's MTA meeting Director Heinicke said that the plans to hold 8,000 and "S" series taxis out of SFO had been shelved.
