Is the "No Left Turn" sign in the Randolph Hills area invisible, or is it just me?

I need to vent for a second about the Randolph Hills traffic patterns. It is wild to me how many people daily just blatantly ignore the "No Left Turn" signs in our area—specifically over by the Liberty gas station and the shopping complex behind White Flint where the Aldi is.

Every single day, it feels like a massive percentage of drivers look right at the sign, decide the rules don't apply to them, and make the turn anyway. It completely backs up traffic for everyone else who is actually following the patterns. Anyone else losing their mind sitting behind these people?
