Firstly, the plate is a nice yellow rectangle, which should make it easy to
spot on all except white and yellow cars.
If you define "centre" as being the central 50% of the width then, *for a
given car* you'll always get the same subset of the registration. It might
be a different subset for different cars, but that's irrelevant.
