Just finished doing the Right Track device with Safeco Insurance. In a three month span I had 12 hard braking, 1 very hard braking, 1 acceleration, and 1 late night ( out past midnight New Years) dings on my driving.
Ended up with 17% discount. From what I can see this discount will be applied on my next bill. I drove about 3500 miles, for me that was about twice as many miles as I normally drive. This was a new vehicle, and I drove like an old lady, because I wanted as big a discount I could get.
I'm Retired, so no driving in traffic or rush hour. The only way I could have done any better was to park the thing for three months. I was hoping to get 20-25%, figured if I really was careful I'd get that.
Over all, still worth it but be prepared for no better than what I got. If I did it again I would borrow someones car, park mine for three months.
