I think a number of people switching from the car to cycle for commuting, do not realise the quiet alternatives for cycling.
I've introduced a number if colleagues to my quiet alternatives and they are often pleasantly surprised at how nice the cycle commute can be. They often remark they were offput initially, as they knew they wouldn't like to cycle the route they were driving.
I setup an intranet site at work for cyclists, which covers all the routes others are using to get to / from the office, with online routes overlaid on mapping, plus written description and times others are riding them. Once they discover the fantastic routes available, worked out by the regulars over many years of tuning, they are converted.
Nothing wrong with high viz and lights, it's my winter commuting uniform. But I do like getting back to normal colours this time of year.
If cars are behind me, I'll wave them on, when its suitable. On my regular commute they know I'll do this and give me a wave. Mind you, only about 6 cars seen on my back lane commute, most days...
