What happened about the 50mph limit on them?
What is it now?
I was behind several recently, they were all over the place.
Admittidly, many people do get a decent sized car & setup to tow one (those 4x4 drivers

) however a lot do not & are all over the place, because they managed to get thier poxy little car upto 60mph+ on the motorway & then drove through a patch of wind that then sends them haywire.
