If the state wins, I wouldn't be surprised if Lyft and Uber pulled out, or at least increased their fares by a substantial amount.
Closing the loophole in the law that lets them treat workers as "contractors" rather than employees is going to torpedo their whole business model.
As an anecdote, I took a Lyft to the airport with someone who had stopped driving for 6 months in order to get started with a new full time job, and had just started driving again to pick up a little more cash on the side. No full time employer would tolerate a 6 month break to start up another job, and then allow you to come back.
