So we are talking about cyclists splitting between the lorry and the curb where a turning truck will use up every inch of free space and perhaps drag a couple of wheels over the curb as well??? That is certain doom. I don't consider riding in the gutter the same as lane splitting although it would be considered filtering. Maybe we have a communication breakdown (language barrier) here.

In the USA, the term "lane splitting" only includes riding on the dashed white lines between the auto lanes. "Filtering" means advancing between vehicles lanes OR next to vehicles curbside. Huge difference in chance of getting rolled over. There is an entire YouTube vid of unfortunate people on bikes, scooters, and on foot getting crushed by turning trucks (wish I had never watched it) as they daydreamed along without a clue. And yes, the truck driver won't have a clue he has run over a person as he rolls along.

Lane splitting trucks/buses is much less dangerous than filtering while hugging the right curb. I agree 100% if this was the intended message.
