yep agreed. i've often been forced to reverse a long way in a horsebox because someone driving a teeny car looks over their shoulder and starts turning the steering wheel at random so they bump into the sides of the road and get their hair off about it.
I am well aware that reversing is in the car driving test and yet people get flustered about it and forget what to do in a car, but I don't see that as an argument to say, oh well, have at it, it's just the same with a trailer on so crack on and don't give a thought to what the consequences may be of being in "control" of twice the amount of wheels
I live in the arse end of nowhere with narrow winding roads too, being able to reverse is an essential but I encounter so many horseboxes (trailers and 3.5t) where the drivers can't safely manoeuvre their vehicles. with precious cargo on, it boggles my brain. We're already at the mercy of other drivers at times, why add to the problem?
