If you find yourself away from the wheel more times than not, a pay-per mile auto insurance company like Metromile may be the best company to go with. Metromile is one of the first companies in the U.S. where a bulk of a driver's premium is determined by how much they drive. How much is too much? We found that generally for Metromile to be a good deal, drivers should only drive 7,500 miles or less per year. The biggest downsides to Metromile is a mediocre record of claims handling, in addition to the company only being available in seven states: CA, IL, NJ, OR, PA, VA, WA.
