GM has announced a new driver assessment program through its subscription-based OnStar service that can offer feedback on how you drive. Think you don't need someone watching over your shoulder and critiquing your every move behind the wheel? Then maybe the program's potential insurance discount through Progressive will persuade you.

OnStar customers will soon be able to enroll in the new driver assessment program, which is exactly what it sounds like. Those who partake in the service will have their driving performance evaluated for a total of 90 days, and after completing the evaluation period, they'll receive a detailed driving assessment. The assessment will reportedly reveal important driving metrics, which will also be compared against those of other anonymous enrolled customers. Based on the individual assessment characteristics, OnStar will be able to provide driving tips. If the driver gives the OK, the assessment will be sent to Progressive Insurance, and depending on driver performance, customers may be able to receive a discount with the insurance company.

GM also makes it a point to say that driver data will only be shared if the customer gives consent. Giving customers a detailed assessment of their driving habits is aimed to help people better understand how they drive and how they can become a better driver. An OnStar representative told us there is also no penalty for Progressive customers who receive a less-than-desirable score.

"Providing drivers with feedback benefits consumers by making them more aware of their driving behavior, saving them money and keeping the roads safer," said Dave Pratt, general manager of usage-based insurance at Progressive, in a release.

The assessment program is expected to be available for all 2016 GM models, most 2015 models, and some 2013 and 2014 models starting this summer.
