Uber has inked a deal with insurer Metromile that addresses a huge question mark: whether its drivers are sufficiently insured between fares. Until now, the ridesharing firm has been giving US drivers $1 million in commercial liability coverage when they actually had a passenger in the car. But when they were heading to pick up the next ride or driving for personal use, the situation was dicier. Uber only requires that drivers use private insurance between fares, but many companies, including Allstate, Geico and State Farm, often flat-out refuse to cover ridesharing vehicles. Uber does insure drivers between fares if private companies won't pay, but limits injury liability to a paltry $50,000 for victims outside the car.
