I have a pay-as-you-go insurance in Canada, and they explicitly say that they "... will not use the data to cancel or refuse an automobile insurance policy; to apply surcharges to your current or future automobile policy or for marketing purposes.".
Apparently, they only use it to confirm the mileage. It does capture your GPS tracking, and will alert you of any issues, like a low car battery (which I've had a few times because I drive so little!).
Honestly, in this case, I don't care. I drive too infrequently, and this saves our family thousands a year, so it's a net benefit for me, and I choose to opt-in.
"thousands a year"? How? I thought driving in germany was expensive and I spend about 2 grand a year with most of that being gasoline. My car is decently powerful and I'm a young man, so I'd expect my insurange to be rather high in price. It's also 'Vollkasko', meaning that all damage to my car is covered as well, regardless of how or why that damage occured
Between my wife and I, we used to pay a minimum of $150 and $200 per month for a single car. That was what we paid, even if we didn't move it from the driveway.
With pay-as-you-go, we paid around $250 for last year, and it'll be less this year.
Our previous insurance was by far the least expensive, so I know it could have been worse. But over the pandemic, where we didn't drive much, it pissed me off to have to pay insurance and not even need it.
Then, when I started cycling more two years ago, I just stopped using the car for pretty much every trip that's less than 30 km way.
