gaz said:i get a lot more respect from drivers when i give a hand wave thanks for not overtaking me at a certain point.
I gave a wave this morning and was awarded with one back. I could hear the car behind me as I was approaching a pinchpoint, took a glance and the motorist stayed. I was going to give them the opportunity to pass as there was plenty of space before the road tightened but she stayed behind me and I went through the tight spot in the primary, she then performed a nice, decisive overtake, giving me plenty of room so I gave a wave and got one back. Some drivers appreciate that cyclists are more vulnerable in these situations and drive accordingly.
I also agree with Rhythmthief, if I see someone hugging the gutter - sometimes a solitary cyclist in club colours (which you tend to see more than you would like - maybe it's the same chap!), I just can't help thinking that they're doing their own thing and not moving as part of the traffic which they normally are. It encourages tight overtakes and you see that from the way other motorists treat them. As always, I give them plenty of room but other car drivers don't necessarily drive with the same appreciation.
