How do you say “hi” to other riders?

Just noticed that fellow bikers wish “wide roads” instead of saying see’ya or bye here. Are there any specific greetings/customs used where you live?

Also, this is about the only country besides good’ole US where riders raise their hands on the road to each other, though it is done in a very specific way: by pointing outward with left index finger, palm facing forward, arm horizontal or slightly below that...)

Just one more thing: it is considered polite to “thank you” car drivers who pull to the curbs so that bikers can filter through - by straightening your right foot outward... Kind of waving but with your shoe I guess that is the only limb that can be freed up temporarily
