Nobody has mentioned this, but possibly relevant is the issue of lawsuits:<p>If a class-action is brought against an Uber, it can be sued out of existence (think like a major case that affects their publicity and kills the business).<p>Even though a local government can become bankrupt, it doesn&#x27;t happen quite that often. It is also easier to police a small subset of bus&#x2F;train drivers and register a known subset of taxi-drivers than having to manage a work-force of in-out ride-sharing drivers.<p>Ride-sharing also doesn&#x27;t seem that efficient, as I&#x27;ve never read&#x2F;heard of an awesome&#x2F;PR+ story of Uber&#x2F;Lyft reducing the traffic congestion in New York&#x2F;London (known as congested cities).
