Oh, that’s common nowdays, as devices in olden days, now just insurers apps (depending on local laws it might only adjust your discounts, not base premium, but same diff). It predominantly lowers claims.

What isn’t common (afaik, that’s my question) is a third party doing that through general data brokering.
A bit like you driving badly on local news, the insurer sees that & ups your premium. It’s accepted with life insurance (bcs tos), but not really non-life car insurance. Idk tho, markets differ a lot.
