Peril analysis is performed for carsharing insurance, i.e., peer-to-peer vehicle sharing insurance. The peril analysis is used to calculate the rate of and/or price insurance for carsharing. A renter may purchase insurance for carsharing (fully, as a supplement or going above and beyond a standard offering, or filling a gap between the minimal level a carsharing company provides and what a driver desires to provide for himself and vehicle's occupants, including comprehensive, collision, or a combination) using a mobile device, an embedded device, a vehicle, or an in-dash unit in the vehicle.
