Also, the RealID and enhanced licenses require a new picture, so those may generate extra traffic. But mostly, it's people who just remembered their license expired at the end of next week.
Also, I think a lot of people just aren't aware of the changes - I happily avoided visiting the SOS for several years before renewing my license two years ago. The previous time I was there, you couldn't add yourself to the line electronically, and there was no texting - you couldn't wander off.
