Brydo we on occasions we tow a caravan, on the motorway we have experienced drivers overtaking us then slow down and sit there in the centre lane totally oblivious to the world around them, you end up catching up they do one of two things, they pull straight across in front of you and decide to slow down or they get upset and speed up as you come alongside them.
The ones I really hate are the one that have a sudden desire to overtake you then sudden pull across in front of you then right down slow down.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
