To repeat an earlier point: TfL have carried out their most thorough
check ever on a minicab firm, and they have found that Uber are
complying with the various regulations. In other words, Uber's drivers
are licensed and have had CRB checks, health and eyesight tests.
They have valid drivers' licences and correct insurance.

The scare propaganda is FUD put out by the black cab trade
because they are not willing to compete in the open market on
even terms and want instead to have their competition made
illegal.
