The whole business model of companies like Uber and Lyft relies on drivers not realizing how little they are getting out of the deal. The ones who do realize - often after some accident that leaves them injured or their cars too damaged to repair - will simply stop working and regret the past.

Gig work usually looks very good when you're starting out and everything is going smoothly. With Uber and Lyft also investing massively in propaganda to ensure their drivers believe AB5 would cause numerous catastophes for their work, it's really not that surprising that most who are actually driving would be against it.
