Now I know this will spark a few comments, but I ride a £99 shopper
bike to get my shopping in, (2000 miles for £99 plus a set of tyres,
cheap, but knackered now so replacement due, so 2000 miles for £150,
no global warming included) I also ride a MTB Marion many pounds more
than £99 and a summer road bike well over a grand. Now in summer on my
expensive bike, good lycra every fellow road cyclist waves, on my MTB
not many on road bikes wave, on my shopper very few wave.

People wave to each other when they feel they are indentifying with a
like-minded member of a minority.

Imagine every pedestrian waving to every other pedestrian on London's Oxford
Street on Christmas Eve. Just as barking mad as expecting /every/ cyclist
to wave to /every/ other cyclist.
