I use two indicators to motorists behind me, both enabled by monitoring a rear view mirror:
1. When a motorist is about 4-6 seconds behind me, I briefly turn my head left, as if I was looking back.. but it is just a very brief glimpse... lets me keep my eyes forward almost all the time
2. When the motorist is about 20 feet behind me, I give a hi sign with my left hand (hand stays on the bar).
When on a four lane road and I see a motorist in my rear view mirror move to the left lane, I’ll often raise my left hand and wave a vigorous thank you.
I think there is lot of value in actively communicating with motorists.
