Not living the UK anymore, I had to check out you said. Typical BBC, spout some emotions over an incidence but not reference the crux of the matter. The UK will need to go through a few generations to produce a real culture change here. It's so overdue IMHO.
Italy, an HGV would not dream of bullying the tiniest of tiny farty Fiat Pandas.
My own experience in France on minor roads, cycling two abreast - a lorry in the distance behind gives a short peep on the horn. We turn around and it's a double articulated lorry working for the foresting industry. It's that type of non-threating peep on the horn to say "look, I'm here". There is no chance the guy can overtake - he and us know the roads. He stays behind us and gives a little short peep prior to the moment when it's a chance to overtake - and we know this too. We single file out and practically ride on the grass verge. The HGV that passes us is a monster. At the end of day the man as job to do against the clock which we are aware of. We get a double peep from the HGV driver in recognition when he passes safely and a token of thanks.
That to me is about sharing the road. Safely with no road rage.
