“IN TOW” Caravans Holding Up Traffic on I10 [Opinion]

I'm so over the "IN TOW" caravans holding up traffic on I10.  It’s an oh-so-familiar sight. You know, the 3-5 cars chained together with "IN TOW" spelled out with painter's tape on the back window of the last car in tow. They're holding up traffic going 10 miles an hour on the interstate where the speed limit is 70. I can see the frustration on every driver's face as I pass them and know I am not alone. Traffic literally barely moved the other day while I was on I10. I seriously thought there was an accident ahead causing the slow-down. No, it wasn’t an accident. It was actually 4 vehicles linked together in tow going MAYBE 20 miles an hour. And then another, and then another, and then another. There were approximately 16 vehicles being towed all following each other on I10. Yes, they were in the right lane, but that is still a problem.

These are the questions I have:  What is the minimum speed on I10?, All I know is there has to be some kind of law for this. Shouldn’t it be illegal?  I’m not trying to discriminate or pick on anyone. I just think this is a serious problem on I10 that needs to be addressed. In a place where we have a law for everything, it seems like this one got overlooked. I honestly don’t care where the cars come from, where they are going, or why. I just know a 30-minute trip should not take an hour if it can be prevented.

This is the only information I could find regarding minimum speed limit and towing:
