How bad an idea would it be to voluntarily give your insurance company your driving data, car location, etc., etc.?
My agent says it would save at least 5%, hardly seems worth it.
It says those who volunteer will save about 10% on liability, medical, collision and comprehensive coverage, reset at each 6-month renewal. It says cuts may go up to 50% "based on how safely a person drives, when they drive, and how much they drive" (i.e., is it less that the U.S. average of about 12,000 miles a year?)."
