Auto insurance companies base their premiums on a host of factors, such as the vehicle, driving record, and, in most states, your age, gender, marital status, and credit history. Some also offer discounts if you agree to install telematic technology on your car, which monitors when and where you drive—and how safe or reckless you drive to get there. Is it worth giving up your privacy to see your insurance bill drop by as much as 30 or 40%?

In this episode, we talk to Michael DeLong, an advocacy associate with the Consumer Federation of America, about telematic data collection: How it works, how it can get things wrong, and whether you should even consider trading your privacy for lower insurance rates.
