I'm a history freak, so I've named my first D22 "Nebuchadnezzar I" (like the name of the vessel in The Matrix).
Wiki explanation: Nebuchadnezzar I (meaning "Nabu, protect my eldest son" or "Nabu, protect the border") was the king of the Babylonian Empire from about 1125 BC. to 1103 BC. He is considered to be the greatest king of the Dynasty of Pashe (also known as the second Isin dynasty), a line which held the Babylonian throne through 12th century BC. His greatest success was re-establishing the Babylonian lands by driving out the Elamite invaders who had taken over much of the territory. He then proceeded to push out and solidify his borders, locking Babylon into a conflict with the Assyrians.
Too long for a numberplate.
