Cars driving into the sunset.

There are pay-as-you-go cell phones and all-you-can-eat buffets, and somewhere in between slots a new auto insurance concept under consideration in California.

The proposed regulations would allow insurance companies to offer coverage plans paid for by the mile, in addition to traditional plans. The idea is to allow consumers to pay for what they use — and potentially save money. It could also encourage motorists to drive less, reducing emissions. The plan could go into effect as early as November.

Under the proposed plan, consumers would be able to report their miles themselves, have their insurance agent check the odometer or visit a repair shop or smog-check station to get a reading. A device could also be put into cars to record mileage readings, though it wouldn't be used to track driver movements.
