Isnt this an argument that helmets are more important for passenger vehicles? After all, car accidents cause about 10x more head trauma in the usa.

Passenger vehicles from this century come with airbags that significantly reduce head trauma. Three point seatbelts have been mandatory in all seating positions for longer, IIRC, and significantly reduce the likelyhood of head vs pavement collisions.

But, if absolute safety is paramount, you do want a five point harness, flameresistant coveralls, neck support, and a helmet, sure.
