That clever little gadget is car insurer Metromile’s ‘Metronome’, a mileage-tracking device that plugs into a car’s data port and reports back to the insurer. Metromile then uses the information to customize its rates.
Metromile’s pitch is straightforward: Your insurance premium should be based on exactly how much you drive. The more miles you put on your car, the more you pay, because the odds are higher you’ll have a claim. Drive less, pay less.
A great example of matching technology and service.
