While certainly impressive, keep in mind that it's only one video showing one of possibly thousands of trials with possibly thousands of difficult corner-case situations where the car got stuck or acted improperly. One video doesn't prove anything, especially not one with a person ready to take over at any moment.
Voluntary data of corner-cases where the car got stuck or acted improperly are available from virtually every company in the self-driving car space except Uber. See the "Vehicle Disengagement Reports" at the DMV's website: https://www.dmv.ca.gov/portal/dmv/detail/vr/autonomous/disen...
