Yes, by all means do so. Just make sure you have the facts in hand.

And please do not conflate the terms root cause with mitigation
The root cause was a bearing. The mitigation method was brakes.

Was the solution to the Ford Pinto problem to issue every driver and passenger a fire extinguisher?
And unlike the Ford Pinto, in this case we have a system (air & dynamic braking) that's worked for decades.

Also it seems you missed the fact that I did, in fact, mention HBD thresholds. It's the very last point in my OP.
