Ah, I did not try to imply that you did. I was actually unsure how you meant it, but just wanted to emphasize anyway, that those regulations are very useful for disabled people. Because in most places, you would just get stuck using a wheelchair on your own. (German trains for example, in most trains you would just not get into - and if you managed to arrive at your destination, you might find out, that there are only stairs and no elevator, despite there should be one. But on this day they maybe changed the lane or whatever, they don't care. I noticed while travelling with a 2 person stroller)
