Yes, all you have to do to get that mythical 30% redux in car
insurance costs is ride with a little Progressive data recorder in
your car. It will measure and report, all aspects of your driving.
P.S.,you won't get any major reduction. P.P.S., they WILL use the
data (and share it) if you deviate from any kind of conformist driving
habits. Read the six or seven "fine print" sections scattered in
their website.
How long (it'll happen in Europe and Canada first) before insurance
companies mandate this?
