Car size is proportional to car owner's stupidity. The dumber you are, the fancier the idea of mindless communication on the road is for you. And stupid people want their message to be the biggest around, but you can't do that while writing normally, so, you get what you get.
At least that's my theory.
Props for trying your hand at Russian. Being a native speaker, only about a year ago did I realize how ridiculously complex the language is. From phonetics, to high context dependence, to word building and conjugation, I commend people who are tackling this abomination.
