One issue for CASA is that the governments have already folded once before over regulations in commercial vehicle operations to Uber. My guess is that there will be enormous political pressure coming onto CASA to get this through. A repeat of what the government did to the taxi/private hire car industry could be repeated in aviation where the government regulated everyone into oblivion then turned around and said that the regulation wasn't actually necessary, hanging law abiding companies out to dry and making a complete fool of itself and its laws in the process.
