I remember somebody bringing up that supposedly people paid large sums of money for low number license plates in Saudi Arabia as "proof" of their vanity. Apparently it happens here too, and probably anywhere else with low number license plates. Goes to show that whenever someone talks about some strange thing happening in far away place, you should always ask if it's even unique to that place.
True, it is pure status-signalling. According to the article, the average price for a 2-digit Delaware plate is $212,000. A single-digit plate got %675,000 in 2008.
As a Delaware native, I can confirm this is something we normally keep an eye out for on the road. I’ve seen a few 2-digit and 3-digit plates, but never a 1-digit.
It may be a vanity/social signaling tactic, but I honestly believe it’s because there isn’t much else to do in Delaware...
I also remember about a decade ago when VEVO on YouTube became a thing, music videos of new songs had in the range of tens to hundreds of thousands of views after a month or so. Now, just this week, BTS released a song that had over 100 million views in just a day or two.
