Heheh. I am pretty sure that when I get my next car, I will get the license plates "TY-144" which is TU-144 spelled with a Cyrillic U.
I figure the way I drive, it's perfectly justifiable to have a supersonic aircraft type for my license plate #.
Of course, personalised plates are a matter of choice. It's a good idea to choose something you really like, because it isn't a simple thing to change it out later. Good luck!
