There’s a reason transportation, especially urban transportation, is public. Many Muni lines would lose money if they were treated as business ventures; they don’t have enough passengers to justify their existence. But San Francisco has a policy of making transit available to everyone, in every neighborhood.
The 8 Bayshore and the 9 San Bruno, for example, serve southeast neighborhoods that badly need transit access – but that likely wouldn’t get an Uber bus.
But Uber is telling Wall Street that its future as a company may depend on its ability to convince people to take private cars and buses instead of public transit, starving transit and ultimately forcing everyone to pay Uber to get around.
Given Uber’s inability to do anything profitable and their admission that if courts start finding that their “contractors” are employees their entire business will go away, I don’t think this will happen… but then, never underestimate the likelihood of some city deciding that outsourcing their public transit system to a company like Uber is a smart privatization idea.
