From the 'Bad Driving' thread, meant ot reply at the time, but thought it's best stripped out of there.
The comment was one from xcm that I found interesting, ebing that if you can ride at 25-30mph then no-one tries to overtake you. Certainly in heavy traffic this may be true (because you'll be going faster than the traffic!), but as a general rule I don't find speed helps at all.
I ride home most evenings round the south road of Arthurs seat and easily cruise at 30mph... With cars constanly up my backside trying to get past, to the extent that when one holds back I make sure to give him a big thumbs up.
Worst I've experienced is probably Orchard Brae where 30mph is even easier to attain and hold, only for people to squeeeeeze past before the roundabout.
I think there's a mentality that says, "That's a bike in front, which must be slower than a car therefore I must overtake."
But I'd be interested in hearing if everyone is the same, or if faster does genuinely mean that people don't try to overtake?
