Explanations about plates - I think the reason is because it's basically customized and over there is no such thing as here in USA having your favorite name on plates or anything.

For example in Russia plates means a lot,,, Plates that starts -AMP- means VIP government person is coming and he could do anything on the road , no rules apply to him basically. Rich people
Buy those plates in order not to obey rules and they don't get fought by police, because they are afraid of them

And btw In Abu dhabi there is plate with -1- And he paid something like 1billion. A lot of people take it as show off but in reality it's Status they live in.
Hope I explained
