I read about this a long time ago - maybe as much as 5 years or so - maybe it's a different thing again???
It seems people were correct it's a cost thing - maybe the EU standard wasn't adopted???
Just as worrying as the poor levels of grip is the vanishing of cats eyes - to me one of the best safety inventions ever. The new stick on ones are totally useless. The old ones were self cleaning but the new ones are so dirty they don't reflect anything - that's assuming they are still in place!!!
There have been a few accidents lately where the corner has specifically mentioned the lack of cat's eyes as being a major factor and yet nothing is being done................
