This is data that will be relevant for every single victim for decades to come and they will pay for this regularly, and it cannot be undone.

What amount per person is acceptable for a thing that simply should never happen?

I don't think "this will ruin my and my bosses life"-levels are over the top at all. Don't wanna risk it, then don't store the data. Usually for most purposes it would be e ough to store that yes, someone has a legit drivers license, which types of vehicles it is for and how long it is valid (if there is a limit).

We don't get to this kind of data reduction if people don't see data as the liability it sometimes is for their customers.
