What are the stupid vanity-plate rules in your state?

There are now slightly more than 500,00 private cars in Hong Kong, which account for 70% of all vehicles. There are 2,090 km of road (318 licensed vehicles for every km), and around 3,500 new car registrations per month. Our roads are clogged and getting more congested with each passing month.

Just for context, 12.2 million passenger journeys are made on a public transport system each day.
