On a national or global scale, insurance is a huge issue. Uber's founder and top officer, is going on an indeterminent leave. Top management is under much criticism for work climate.
Riders have Lyft to pick, and Uber might just take a tumble.
All this, before the insurance topic kicks in.
When drivers renew their Personal vehicle insurance policies, it is increasingly likely they will be required to stipulate, the vehicle is NOT used for commercial purposes, like hauling people or goods.
When the driver sees he is NOT insured, for such activities it is possible many of them will give it up, rather than purchase prohibitively expensive extra policies.
IOW just what the taxi companies lobbied the insurance companies, to do. It is a questionable business model in the long ru.
Uber has never made a profit.
