Its pretty disappointing that transit advocacy groups spend more time fighting ride-share and jitney transit services than actually working to improve transit in their cities. Instead of looking for solutions to making faster, cleaner, more reliable transit more feasible, they're blaming riders and ride-share companies for a 5% reduction in ridership.
But advocacy against ride-sharing is probably a good use for mass transit advocates' time: this trend drains the financial resources from mass transit, it further reduces the group of people interested in public transit to the poor, who have less political influence. And it creates more traffic, where now even more often a bus with 60 passengers is held up by three cars with one passenger each, preferably blocking traffic while unloading.
