A person in the insurance industry told me the mfg's of several companies are now using these to fend off lawsuits, someone piles into another car this box can tell speed, time if any on brakes and a lot of other info, also very good for the insurance industry claiming driver error. Also a tracking device for law inforcement. Big brother has gotten even bigger lol.
