An insurance policy should not contain provisions that allow one side or the other to unilaterally void the contract in exchange for benefit. Provisions that void the contract for failure to perform or for fraud or material misrepresentation are ordinary and acceptable.
The basic idea of telematic auto insurance is that a driver's behavior is monitored directly while he or she drives and the information is transmitted to the insurance company. The insurance company uses the information to assess the likelihood that a driver will have an accident and adjusts premiums accordingly. A driver who drives great distances at high speeds, for example, might be charged a different rate than a driver who drives short distances at low speeds. The precise effect on charges is not known as it is not clear that a high speed long distance driver incurs greater risk to an insurance pool than the slow around-town driver.[citation needed]
