"Our computers would have recorded, sounded an alarm at each overload attempt and refused to move after a preset number of trys. Some required a keyed reset after reaching those numbers of trys...this is why said pretty soon, OEMs will control more to all ratings like they now do with ICE rev limiters"
Not quite the same but as a young buck installing piping on a natural-gas-fired-steam boiler-steam turbine power generating plant, I was in the plant when a series of out of spec issues (low steam flow on one turbine, excess on another, failed gas valve delivering full fuel to a boiler running at 40% capacity, etc) resulted in an automatic system "shutdown"....the most dramatic effects of which were the steam blowdown (wherein a 10" sch. 80 steel line wiggled like an RV hose between supports spaced circa 80' apart) and the max capacity gas flare. Lots of shiny lights and interesting sounds.
An out-of-spec truck trailer combo won't result in the same sort of fireworks, but at the end of the day, one has to decide whether they will stay in spec or not. Hopefully if they go out of spec, there is some analysis behind that decision.
