> escalating multiplier for reoffense within the same category of offense with a cool down period of a few years if they don't break the law.

My country - Poland - implemented this part a couple of years ago. Specifically a reoffense in the same category within two years results in a higher tier fine - about twice the usual amount. Fines were also adjusted for inflation after over 20 years of being nominally the same.

The rate of cars passing me doing 180km/h+, so 40km/h+ above the local 140km/h limit, fell drastically.

Particularly speeding cars in poor condition (like dangling linkages etc.) vanished. Nobody wants a ticket that's worth more than the car.
