Progressive Insurance offers a similar product, but the way the collected data is used isn't precisely defined. For example, it may try to raise your insurance premium if you exceed the speed limit, even though you're keeping pace with traffic flow (a common situation in the US).

I actually participated in the program a couple of years ago. You used it for 6 months and it monitored your driving looking for things like rapid acceleration/deceleration -- I assume that's what leads to most accidents. It also tracked time of day as an indicator of how risky you are to insure. When I used it, it was only used to discount your insurance if you were a good driver by their metrics, not increase any premiums.
