Tim from GPS Review revisits the idea of submitting a GPS tracklog to your insurance company to prove you are a good driver in exchange for better rates. This particular program is in the UK called "Pay as you Drive". David Starr talked about a similar program in Canada a couple months ago.
I still think this is a good idea. In order for GPS to be profitable in the consumer market, the end person being tracked must be in full control. In both of these cases, participation is voluntary and the consumer is in full control over who sees their data.
As long as rewarding volunteers doesn't turn into punishing non-volunteers, then I encourage these programs. I can see the commercials, "Where's Tim can save you 15% or more!!"
I'm curious to hear Jerome Dobson's opinions on this.
