Thanks for all the great links.
I used to travel fairly often between Dallas and Austin, TX. Each time there were always several long southbound convoys of cars towing other cars, all driven by Latinos. These were older and usually smaller cars. I often wondered where they were coming from and if they had been bought at auction, stolen, or what and what their intended use was.
I haven’t travelled that route in several years but I imagine that started before I noticed it and that it continues today.
