<prompt> Human: Hi all,I have a car, but I dont drive much. I bike to work and back, and also to the grocery store and around town. I drive maybe 50 miles a month. Im currently with Geico and paying 100 a month for somewhat decent coverage in the San Francisco Bay Area. Money is always tight, so I try to cut corners financially whenever possible. I found a company called metromile that seems promising for someone in my position. After selecting my coverage, the base rate is 48 a month plus 7.2 cents a mile driven. If I drive over 150 miles in a day, you no longer pay by mile for road trips and whatnot. All said and done, if I drive 50 miles a month Id pay 3.60 plus the 48, so a little over 50 a month. That would save me around 50 as well. I have questions, like how do they determine my mileage? Are there any other catches? Has anyone here used a service like this before?Thanks.EDIT: Someone in this thread gave me the idea to call Geico and ask about mileage. Theyve changed the main use of my car to pleasure and have adjusted my annual mileage to 1,000 miles a year. My new monthly payment is 60. I am going to sit on the idea of getting rid of the car for a month or two. Thank you for the help, PF!  <response>: Im using metromile. They use an OBD2 device to measure your distance. Only used for 2 month - I dont know what the claim experience is like. I drive less than 200 miles a month so its saving me a lot of money.
