The business of underwriting is all about estimating the risk of loss. In broad generalities, that means a red mean-machine driven by a teen is likely to be involved in an accident, whereas a family saloon driven by a homemaker with a baby in back is likely to arrive safely. Although stereotypes are not always helpful, there are some very detailed statistics showing which drivers are most likely to make claims. Not surprisingly, the people who only drive occasionally and at off-peak times when there’s little traffic on the roads have the lowest accident rate. When the statistics confirmed this common sense assessment, insurers wanted to offer low mileage drivers a substantial discount. Unfortunately, large numbers of people are dishonest and claim low mileage simply to get the discount. Faced with this problem, most insurers either refused a discount or only offered a token percentage.

Technology has now come into play. Many new vehicles leave the factory with on-board computing power and transmitters. In the more sophisticated vehicles, this allows the vehicle to signal a garage when maintenance work is required. This technology can also be modified to monitor when and how the vehicle is driven, transmitting the results to insurers. For vehicles without the basic technology installed, black boxes have been developed. They can be plugged into the vehicle’s electronic systems and collect all the relevant data.

This is Big Brother technology to tell the insurer exactly when you drive and how many miles you travel. But it solves the problem of dishonest reporting. So many insurance companies are now offering plans directly based on the mileage traveled in a week. This is of immediate benefit to homemakers and seniors who only make short trips during the day. The most honest of the insurers are offering up to 40% discount to those who use the vehicle the least. It also helps the environment by encouraging people to use private transport less. If people walked more, it would make us less dependent on imported oil. It also reduces pollution. With better air quality, people with breathing difficulties have a better quality of life.

Not everyone approves of this technology. It’s considered an invasion of privacy. Indeed, with the right software, the insurers and anyone else who has access to the data will know exactly where the vehicle has been driven. This could prove involvement in criminal activity or suggest infidelity. Of course, the insurers protest they have no interest in making this data available to law enforcement agencies or anxious wives. But there’s a case about to be considered in the Supreme Court where monitoring a GPS transponder evidenced involvement in drug dealing. It will be interesting to see what our highest court has to say about this use of the technology.

As an example of an insurance plan, State Farm are promoting a Drive Safe and Save Plan in Illinois. This is based on the installation of a plugin device called In-Drive. Effectively, this enables drivers to pay for their insurance by the mile. Car insurance rates can be significantly lowered if you are prepared to accept positive monitoring of your driving. Look for the option the next time you get car insurance quotes from the top insurers. Big savings are available.
