I think you have to take all car reviews with a pinch of salt, especially if conducted by humans. Firstly, no human can exactly replicate the test to match another humans efforts, speed of eye, reaction and thought will differ wildly between two individuals. Unless the test is carried out by a robot or machine, its never going to be accurate.
Secondly, as has already been said, where is the value of testing the vehicle with its safety systems turned off. How many of you jump into the car, and turn them off before towing.........none.
Thirdly, who are the "professionals" that write this drivel in the first place and what makes them "professional". They can drive a bit and write a bit, so what. They havent passed any different test to the rest of us, and in many cases have less training than the rest of us. I would think a large number of experienced caravanners on this forum are easily their match in ability. We have current and past HGV drivers (LGV if you wish), coach drivers, police drivers and military trained drivers, all on this forum, and we are prepared to listen to driving advice from a journalist. No siree, I will put my trust in my own experience rather than listening to somebody who probably will be advising on cookery next week.
And finally, everybodies opinion will differ on what they see and feel in a towcar. Its all in the eye of the beholder.
I think you can probably guess that I am sceptical where any form of journalism is concerned.
