No you've got to wave, or you're not cool. Failing to acknowledge the other rider is uncool. However, to be cool your acknowldgement must be nonchalant, and more subtle than the other rider's acknowledgement.
Hence, the slight finger wave by racer types.
The most subtle acknowldgement wins. So you want to make the absolutely smallest move with your finger possible, that is yet perceptible.
