People seem to forget that "professional driver" is an actual job available for close to a century now if you really wanted a full-time position. Uber already works with FTE drivers at higher tiers like Lux and Black.
All of the drivers I've asked over 1000's of rides have said they prefer the freedom and flexibility to work on their own time. Yes they want more money, but not at the cost of the flexibility. They already have day jobs, or are students, retirees, business owners, etc, and are making extra income with an opportunity that wouldn't otherwise exist.
Perhaps the tiny handful of people who are suing to become employees should just go out and become employees instead of trying to change the rules for everyone else.
