Why the snide?
Taxi service regulation is left to member states to work out, not the usual Brussels bureaucrats.
Most regulation is national and managed by national bureaucrats. Brussels only becomes involved in questions of the single market. Hard to see that for taxis to be honest.
Uber is a fairly parasitic business that essentially relies on arbitrage between regulated and unregulated parts of the market. ie. insurance, minimum wage, quality of driving, criminal record, etc. That's not to say that some taxi markets aren't victims of restrictive practices: the synthetic distinction between taxis and private hire in the UK springs to mind.
