I always give a wave and if necessary a toot of the horn. Most wave back, although there are a few here and there that must not be "People of the Fire" . I see a few here and there in my area but it's usually no more than once a month == and it may be other the other side of the highway.

I do get other people to wave though --- but most of the time it's watching peoples heads swivel like the girl on the exorcist ...........as I fly by.
