"Baby on board" - and there was - driven like a lunatic accompanied by midlife crisis witches shouting, jeering and swearing like, well probably like the people they were.
Driver on the M1, was in left hand lane, I had been coming up behind him. Driver then proceeded to drift over in to the middle lane, without even so much as an indication. I had to swerve into right hand lane to avoid being hit. Driver did not apologise.
Dangerous undertaking and pulling out into fast lane directly in front of us on A38
