My question is, "Why?"
Most of the time, including in the picture from this article, people would be towing something like a camper. To go camping. In a remote area. Which has no WiFi to begin with.
For generations, a hitch has been a sufficient tool for towing shit. I guess its simplicity just doesn't allow enough avenues to monopolize from. I can't possibly think of how Wi-Fi towing solves more problems than it causes, other than charging the consumer for shit they don't actually need.
