We all understand if you're doing uber, you need to tell your insurance company that you're doing ridesharing and they'll update your policy to include that and if you don't tell your insurance company, any claims will be void.
Is it only void when you make a claim during the ridesharing service? If you do ridesharing Monday, Tuesday and personal Wednesday, Thursday, and Friday. If you got into an accident on Friday and you don't tell your insurance company about your ridesharing, are you still covered?
Need to understand risks and what you're paying to the insurance companies.
This is a question of understanding what are the risks. Whether to take the risk or not is a separate question and isn't being asked here.
I wouldn't want to take the chance - insurance companies always seem to win.
