Keith, I've never actually been a European citizen ... but it seems odd to have both a Welfare State and individual "shared" entrepreneurship at the same time. There are good reasons besides driver income that taxis are heavily regulated in cities all over the world.
At this point, Europeans say that the tax and benefit structure is preventing employers from hiring new people. But in Germany, forced, imposted, directed, "job-sharing" (reducing everyone's hours to keep full employment) was a big factor in Germany's relative prosperity. On the other hand, punishing, Puritan-punitive "austerity" pushed by the, er, Lords, of England have caused vast amounts of pain, and the opposite of "gain". Do you really want to institutionalize subsistence-level entrepreneurship? Sounds like they've pulled the wool (barrister's wigs) over your eyes.
