He(?) has seen some bikers around the summit of Cairngorm and thinks that if it gets popular then there’ll be increased erosion. Some of the counter-arguments point out the very low numbers of bikers that make the effort to get up there.
It would appear unlikely that the current infrastructure, the funicular, would ever be opened up to take bikers up to the plateau. I believe that they don’t take skiers up there, or at least allow them to ski from the top station.
Seems like someone has got a bee in his bonnet and is letting off steam while refusing to let facts, such as they are, get in the way.
