The black cab dislike of Uber is close to the DOO debates on Southern -
technology is obviating the need for a job, and those in that job
understandably don't like it.

In London it's much more than that. One of the black cab's main
complaints is that Uber cars illegally (as in "waiting") congregate
outside various venues, and as well as in effect being hailed by people
leaving the venue, block the parking/kerbside so black cabs can't be
easily hailed, or drop off.
