Interesting. I wonder what consequences this will have in the british market(IIRC it being one of their major hubs in Europe). I don't think they'll pull out at this point though, but will make it marginally impossible for new drivers to be accepted (unless demand increases dramatically but I don't see that happening either due to "current events")
One thing worth noting is that the UK is already a little different from the US, because Uber drivers are required to have a private hire license issued by the city where you're operating.
For example, in London you'd be required to have a full criminal background check, a medical examination, and pass a "topographical skills check" (basic route planning and map reading).
So it wasn't like you could just apply to Uber and be up and running within a few days to begin with.
