If Uber wrote a new contract, with greater autonomy and less direction for its drivers, it's quite possible that it would be upheld as genuine self-employment; the ruling covers the workers' current arrangements. So that route is feasible if Uber is willing to cede its control. I think that somewhat unlikely.
