Distance
Some car insurance plans do not differentiate in regard to how much the car is used. However, methods of differentiation would include:
Reasonable estimation
Several car insurance plans rely on a reasonable estimation of the average annual distance expected to be driven which is provided by the insured. This discount benefits drivers who drive their cars infrequently but has no actuarial value since it is unverified.
Odometer-based systems
Cents Per Mile Now[13](1986) advocates classified odometer-mile rates. After the company's risk factors have been applied and the customer has accepted the per-mile rate offered, customers buy prepaid miles of insurance protection as needed, like buying gallons of gasoline. Insurance automatically ends when the odometer limit (recorded on the car’s insurance ID card) is reached unless more miles are bought. Customers keep track of miles on their own odometer to know when to buy more. The company does no after-the-fact billing of the customer, and the customer doesn't have to estimate a "future annual mileage" figure for the company to obtain a discount. In the event of a traffic stop, an officer could easily verify that the insurance is current by comparing the figure on the insurance card to that on the odometer.
Critics point out the possibility of cheating the system by odometer tampering. Although the newer electronic odometers are difficult to roll back, they can still be defeated by disconnecting the odometer wires and reconnecting them later. However, as the Cents Per Mile Now website points out:
As a practical matter, resetting odometers requires equipment plus expertise that makes stealing insurance risky and uneconomical. For example, to steal 20,000 miles (32,000 km) of continuous protection while paying for only the 2,000 miles (3,200 km) from 35,000 miles (56,000 km) to 37,000 miles (60,000 km) on the odometer, the resetting would have to be done at least nine times to keep the odometer reading within the narrow 2,000-mile (3,200 km) covered range. There are also powerful legal deterrents to this way of stealing insurance protection. Odometers have always served as the measuring device for resale value, rental and leasing charges, warranty limits, mechanical breakdown insurance, and cents-per-mile tax deductions or reimbursements for business or government travel. Odometer tampering—detected during claim processing—voids the insurance and, under decades-old state and federal law, is punishable by heavy fines and jail.
Under the cents-per-mile system, rewards for driving less are delivered automatically without need for administratively cumbersome and costly GPS technology. Uniform per-mile exposure measurement for the first time provides the basis for statistically valid rate classes. Insurer premium income automatically keeps pace with increases or decreases in driving activity, cutting back on resulting insurer demand for rate increases and preventing today's windfalls to insurers when decreased driving activity lowers costs but not premiums.
GPS-based system
In 1998, Progressive Insurance started a pilot program in Texas in which drivers received a discount for installing a GPS-based device that tracked their driving behavior and reported the results via cellular phone to the company.[14] Policyholders were reportedly more upset about having to pay for the expensive device than they were over privacy concerns.[15] The program was discontinued in 2000.
OBDII-based system
In 2008, The Progressive Corporation launched MyRate to give drivers a customized insurance rate based on how, how much, and when their car is driven. MyRate is currently available in Alabama, Kentucky, Louisiana, Michigan, Minnesota, Maryland, New Jersey andOregon. Driving data is transmitted to the company using an on-board telematic device. The device connects to a car's OnBoard Diagnostic (OBD-II) port (all automobiles built after 1996 have an OBD-II.) and transmits speed, time of day and number of miles the car is driven. There is no GPS in the MyRate device, so no location information is collected. Cars that are driven less often, in less risky ways and at less risky times of day can receive large discounts. Progressive has received patents on its methods and systems of implementing usage-based insurance and has licensed these methods and systems to other companies. Progressive has service marks pending on the terms Pay As You Drive and Pay How You Drive.
