You're right on the money Rich
We're accustomed to looking for multiple headlights, tires and wide front ends. A motorcycle is a single track vehicle and much more difficult to see.
I never used to "assume" they saw me as I approached.
High beam headlights, and flashing or wig wag head lights go a loooooong way toward being seen
If you don't have the wig wag conversion, I'd suggest looking into investing in won. If I ever owned another bike, it'd have them...guaranteed
Glad you and your bikes ok.
Sounds like you did everything right
