Not to sound like a Chipwrapper reader, but...
I've almost been taken out by people on BSOs and folks in lycra while crossing the pedestrian bridge at Millhill in Musselburgh. Despite a big blue sign asking cyclists to dismount.
I've also had more than a few close passes when coming through the pend from Kerr's Wynd through to the High Street (down beside the old Musselburgh Arms hotel). Again, a mix of teens on full-sus BSOs and people riding pretty high end MTBs and road bikes. Again, big sign asking cyclists to dismount. All-time classic was a guy who bombed it through the pend, hit disc-brakes when he came to the kerb, then rode on up the pavement past the newsagents and then skirted the Indian takeaway, dodging various people.
The footbridge adjacent to the Electric Bridge is shared use but signs request cyclists to give way. This is my route to/from work 5 days a week and has been for the past two years. In my experience, cyclists rarely give way. One guy seemed downright annoyed when I dismounted as there were parent peds and mini-peds walking across the bridge.
'You're allowed to ride on the bridge you know' he said rather petuantly. I simply pointed to the peds.
