Whether or not YOU believe this, doesn't make doing it when it's contrary to the law, right or acceptable.
I wouldn't want to risk my passengers, other road users or my boat by having to brake very hard at 60mph++when towing - you can't predict what the trailer will do (or what situation other drivers might put you in). Even on a motorway you are not always driving "in a straight line"
How do you know the trailer's well maintained - bearings can fail unexpectedly, or know your real ability to control the rig if you have to brake hard and unexpectedly.
It's the sort of argument "I'm a good driver so normal laws designed for others less capable than me don't apply." I don't agree, and am speaking with 30 years experience in the transport industry and used to dealing with 44t semi trailers - much more than a rib behind me. I've seen the impact of excessive speed / poor handling within the industry. Stick to the rules, it doesn't cost much time.
Now climbs off soapbox.
