This seems to be a general problem across the peer-to-peer rental industry. My friend had her car stolen while renting it out on Getaround and ended up in a similar situation.
These things seem to come and go in cycles. Airbnb and Uber faced several similar trust & safety issues of their own before they started building in much stronger safety and insurance protections and, crucially, convincing their customer base to continue trusting them. Now that their hard work has once again given people confidence in the P2P rental model, these upstarts are swooping in with none of the protections and reaping the benefits.
