Since we're going with car analogies, it's more like a company leases a fleet of vehicles where each vehicle can be driven up to 20,000 km/year for the price negotiated. However, the cars don't have odometers to keep track of distance traveled. The dealership who leased the cars thinks that they've been driven further and complains to the Department of Transport. The DoT investigates and adds up third-party records of everywhere the cars have been and finds out that some vehicles were routinely driven more than 20,000 km in the prior year. The company agrees to pay the agreed-upon rate for any overage distance per vehicle plus a proportional fine and also agrees to add an odometer to the vehicles to track actual mileage in the future.
