Assuming that the function that generates the plate numbers from the current time and a per plate seed is deterministic this shouldn't be a problem. You tell the police you saw the car with plate 2XYZ345 do a hit on run and give a time range. The state would have the seeds in its plate owner database and could generate a list of all cars that had 2XYZ345 sometime in that time range.
