@Ac - that's not good at all... :-(
This morning I witnessed a horrid, low speed punishment pass of the cyclist by a coach at Drumbrae Roundabout this morning.
Heading West I stopped behind a stationary queue of coaches where it was still 2 lanes (just before it splits into 3). A man on a bike went up the inside of the coaches and into the newly formed lefthand lane. The coach alongside him, who was going straight on and should have been in the middle lane, slowly crept to the left until he was about 2 foot from the kerb/railing with the cyclist in between.
Horrible to watch - can only have been deliberate. Fair enough to cross into the left lane to give yourself more space on the roundabout, but to go that far over the line must have been connected to the cyclist being there.
