> Most people never think twice about the random mix of letters and numbers the DMV assigns them.

I started thinking about it when someone parked next to me in a nearly-identical model - same brand, year, etc, the only difference was some roof accessory - and a nearly identical license plate. (Think ABC D12 and ABC E12). I started trying to open their car door, and was confused until I noticed some things in their front seat that were clearly not ours.

Later that week, I was shopping around for car tires, and saw that some shop - PepBoys or something - let you punch in your license plate and let you know what kind of tires you need, and that their API response included the car make and model. I thought about poking around it, and seeing if there was a pattern to the way my state assigned license plates, but never got around to it.

(They live in town, too, and I've seen where they park. I should go introduce myself to our car twin.)
