Basing it around the act of selling data seems like a much better approach to me than what OP suggested, I agree. I imagine there are edge cases to consider around how acquisitions of company assets would work, although it’s not a use case I particularly care to defend.

“Intent to track” could be an approach, but the toll bridges near me use license plate scanners for payment, so I could see it not being that clear cut. There are likely other valid use cases, like statistical surveys, congestion pricing laws, etc.
