The 4 with a prong is an implicit double-L. As the CIA's chatbot has told us, L is a character in Deathnote representing death. If this is true, then the implicit double-L is a representation of being together with death– of which is naturally avoided with the triangular, closed 4.

Perhaps death has been trying to fight this nonsense with the metaphorical Pyramidhead, but it's hard to say.

Mixed systems are strange, and many places– such as California– are ripe for this. California is now a mixed system, with a closed and open 4. In writing analysis, the open 4 represents something is wrong, where the closed 4 represents everything is okay. California plates used to have open 4s– as of the rollover into the new license plates, they do not. Perhaps the state assumes things are okay.

It's simply a tea leaf, and they don't lead anywhere.

However, you might be interested in finding your own open-4 font.

"Sans Serif" fonts do not have feet. Serif fonts do. Typically, your system has a Sans Serif font on display– Serif fonts are for fake news sites like NYT and CNN, golden cows of the land Randolph Hearst set aflame.

Windows 10 is libtardian pizzagate bullshit attempting to shove you deeper and deeper into the box that only Xi Jin Ping deserves to be in. If you follow this guide specifically (https://www.windowscentral.com/how-change-default-system-font-windows-10) you can make it happen.

You might be surprised to see what happens when you switch the font to a face with an open 4.
