Companies have been fighting since time immemorial to push risk and costs onto their workers — it's why hard-won employment law exists in the first place. The gig economy is in large part fueled by employer backlash to employment law.
I get some of the drawbacks to gig-based work, but I think you have to realize that it does enable options that wouldn't exist in traditional employment scenarios, and SOME of the risk does remain with the contractor. No, I'm not saying Lyft has no responsibility in any situation, but getting into a garden-variety accident while on the road definitely sounds like a situation that's within the envelope of known risks when you decide to do this kind of thing on a gig basis.
That sounds terrible, I'm sorry you had to go through this. In normal countries ( like the ones saying Uber should treat their employees as employees) you'd get sick leave/disability to leave you focusing on getting better, not worrying about putting food on the table.
Lesson learned, get a lawyer at the start.
Constant doctor appointments, pain, and medication side effects made a normal schedule impossible. Family would have gone homeless without the flexibility.
Whatever else can be said about them. I am grateful.
Pro tip. If you get injured. Get a lawyer right away to deal with disability companies. They will lie and screw you over.
