MEXICO CITY (AP) — Thousands of medallion taxi drivers have parked their cars to block major Mexico City thoroughfares to protest ride-hailing apps such as Uber.

The ranks of white-and pink cabs caused major, hours-long delays for motorists Monday.

Taxi drivers say they have to comply with requirements for licensing, tax, inspection and tests that the ride-hailing apps don't have to endure.

Eduardo Elizalde is a veteran with 40 years behind the wheel of Mexico City cabs.

He said drivers "want the laws enforced. We are not against anybody. But just as we have to pay taxes and pass exams, so should the apps."

The city of 9 million has about 140,000 medallion cabs, and probably that many ride-hailing cars and gypsy cabs. New entrants like the Chinese app Didi have swelled the ranks.
