For some reason I started reading those lights in Morse.
Chevy hit the Morse Aptronym jackpot in '65.
The Chevy II had .. .. = ii.
The SS (and other Impalas) had ... ... = ss.
If you read vertically and diagonally, you can see more complicated patterns.
'60 CaDDy = DD. '57 Plymouth = NA. The absolute zenith of Morsable cars was the '42-48 Buick. If you start from the reflector and read through taillight, directionals/stop, taillight and reflector, you get ENKAE. Doesn't spell anything, but it's complex enough that it could have been used for steganography. Some modern cars with patterns of LEDs and sequential flashers could send whole paragraphs.
Polistra is talking about Caddies.
Question: Is there a car that could spell its own name if it wanted to? I can't find any 'serious' examples. All four-cycle engines are 'Otto-cycle' engines, especially in German; but no actual car was called Otto. [Oops, spoke too soon. Google spinoff is developing on Otto-nomous truck!] Brazil had a modified Lotus called the Emme. That's about it for fully symmetrical names. I think the longest Morse palindrome is 'waiting', but that's an unlikely car name except maybe in Japan. Austin comes DAMN close with just a slight gap in symmetry. Labels: Aptronym Alert, Danbo
