I'm not claiming it's balanced, I was just looking for a quick reference to some of the allegations made.
Point is, Uber and Lyft have disclaimed responsibility because its drivers are all independent contractors and so the companies are not accountable for their actions, whereas taxi companies have an interest in (a mandate to) bonding and insuring their drivers.
All Uber drivers are insured by Uber when they are "on the clock" (have the app on). When the app is not on, their regular insurance covers them.
Obviously Uber isn't perfect, nothing is. I have issues with some of their policies and actions, but the taxi people are worse. Again, it's not their fault (well it is when they beat up Uber drivers, trash their vehicles, or block the roads in a hissy fit) as it's the system that's broken.
