Taxis - Black Cabs, Uber, Illegal Cabbies

I'd like to know what these issues which have potential public safety and security implications are - this seems to be more about TfL trying to screw as much cash as possible out of Uber as possible.

(From elsewhere: https://news.ycombinator.com/item?id=15310969) things like:-

Failure to follow up DBS (criminal records) checks (can't find an article about that one).
