I would estimate the area of the weld is considerably greater than the area of the screw thread in eye in the Exeter registered tow vehicle, though probably the material is less strong. The 8mm thread on a mild steel chinese christmas cracker exhaust clamp would strike me as the weakest link. But to top it off, its survived a proof test.
As for a bar approx 8 foot long 'digging into the road' - poppycock. The towing eyes in the towcar are certainly designed for towing/recovery of the tow car, having a chummy at half the weight hanging off it should cause no cause for alarm. The bar is a item marketed commercially for such eventualities designed to use the towing eye.
That said if it did fail the bar would certainly go towards and under the wheel and cause some excitement, but I doubt our friend in the chummy was being towed at anything much more than 20mph. It would certainly have been the fastest the chummy will have ever slowed down!.
