This is a very good topic. I am a bike rider and drive a golf cart. There are good respectful riders and respectful cart drivers and unfortunately there are bad ones as well, as in anything…and give us cyclers bad reputations. Extra efforts on both parties keeps everyone safe.
When I ride either on MMP or public roads I wave on following cars/carts just like you do. Like wise, on narrow lanes I extend my hand down beside me with my palm facing the follower to signal…” wait please “ then wave them to pass…then usually I get a “thank you honk” in reply. Likewise when I pass walkers, I ring a bell so as not to startle then and then say “biker on your left”…usually they slide to the right, and some say thank you.
It’s called defensive riding/driving…works both ways.
Again, good worthwhile topic.
