I was on the motorway today. Fairly busy but fluid and freely flowing traffic.
I was travelling at about 55-65mph in the slow lane. I wasn't in a hurry and found myself approaching a car +caravan in lane 2.
As I was doing an acceptable and safe motorway speed and I was in no hurry I decided that I wwasn't going to weavve out to lane 3 to overtake and I wasn't going to break the law by 'undertaking'. I was also approaching my junction. I sat behind the caravan in my lane (ie ensuring I wasn't in the caravan blind spot).
An HGV approached from behind, and continued to drive in my estimation, less than 2 car lengths behind me. It was so close that all I could see in my mirror was the radiator grill. I literally could not see his winscreen. I could not see the number plate.
I touched my brakes gently couple of times to indicate that he was uncomfortably close.
A couple of minutes late rhe was using his horn to tell me to move.
As it was a 4 lane motorway it would have been legal for the lorry to move out to lane 3 if he was tgat desperate. Meanwhile I felt intimidated and unsafe.
