1) the test has value and the driver's can remain a premium service, maybe even get added to uber like cabs in San fransisco
2) the knowledge is not if value and should be ditched.
I hear a lot of cab advocates trying to have it both ways. "it's no fair, our service is so much better because of the specific cars and the test, but uber drivers don't". If the service was so much better, there wouldn't be an issue, it's been a while since I was in London, but in northern Delaware, Philadelphia, and NYC, uber is far better than the cab companies. Probably because they know pulling bullshit will get them a low review and out of the service. In my location, I'd pay a 10% premium to use uber over cabs.
