@skyfaller asks:
Q2. What is the most #sustainable bike helmet?
I was sufficiently impressed by Coyle "Tree Piece" custom CNC'd wood & cork #helmets to put down a deposit: https://coyledesignandbuild.com/
But they have issues aside from cost: 4-5 months wait and "we don’t know how you would test one-off creations when five identical samples are required for lab testing to the CPSC standard": https://helmets.org/helmets-by-brand/#coyle
Anything else not just recycled plastic?
