I wonder if "insurance for a cut" is a thing. Basically apply the credit card model to insurance for cabs. Insurance company takes X% of all rides for providing the proper insurance needed for said rides. Keeps the barriers to entry low (giving up a cut is easier when you just do a couple of customers on the side than having higher fixed costs) and would probably allow a smart insurance company to make a nice bundle of money.
