As both a part-time cyclist on Mull and a driver I have sympathies with both. Some things cyclists do here I've seen make your hair stand on end. We have only 20 miles of double track here, and only 3 places on that double track where it's safe to overtake another car. So you can imagine the frustration when you're heading for the ferry and 2 or more cyclists hear you coming and suddenly swing out in front of you, to force you to overtake wide. The only trouble is, as a local, you know you've got another 5 miles to go before you can overtake safely, so have to lose maybe 15 minutes. I've actually been taking a sick child to the hospital and slowed down by this. So that's the first thing to realise. When I'm cycling here I pull over if I'm not at a safe overtaking place, but so often visitors (sadly usually central belt Scots - the English tend to be a bit more humble) won't do this. Secondly, it's not unusual here to have a cyclist toiling uphill in front of you at 2 or 3 miles an hour on a single track who refuses to pull over at the next passing place to allow overtaking (which is actually illegal). The third and most terrifying thing is the cyclist who is inexperienced and suddenly loses balance and lurches out in front of you (often without a helmet). I'm a cyclist too, we like to see cyclists, but it would be good to see a bit more humility and an understanding that - even if you're a Scot - there might be lots of local knowledge about roads that you don't know. I noticed that someone talked about a driver heading right at them. It's normal practice for local drivers to maintain their usual speed here on single tracks when approaching one another, and time their passing to coincide with a passing place. To the newbie it looks like there's going to be a head-on collision. You get the hang of that after a couple of years. I can see why cyclists find that scary, but local driving here is actually actually exceptionally good and courteous most of the time. Cyclists do also need to realise that this is a working island and those here for leisure should have the courtesy to give way for that.
I'm sorry, I can't agree with most of your statement. I've driven an 8 wheeled crane truck on the island and know the roads fairly well and have never had an issue with cyclists even during the busy season when that ferry is crammed full from morning to night.
