Findings afrom the HURT study (source linked there) indicate many motorcycle crash shtuations where High-Viz PointTwo Air Vests and the protection of an air vest can save reduce injuries and save lives.

Several of the findings are noted here:

Motorcycle Accident Cause Factors and Identification of Countermeasures, Volume 1: Technical Report, Hurt, H.H., Ouellet, J.V. and Thom, D.R., Traffic Safety Center, University of Southern California, Los Angeles,

7. The failure of motorists to detect and recognize motorcycles in traffic is the predominating cause of motorcycle accidents. The driver of the other vehicle involved in collision with the motorcycle did not see the motorcycle before the collision, or did not see the motorcycle until too late to avoid the collision.
 
14. Conspicuity of the motorcycle is a critical factor in the multiple vehicle accidents, and accident involvement is significantly reduced by the use of motorcycle headlamps (on in daylight) and the wearing of high visibility yellow, orange or bright red jackets.

18. Conspicuity of the motorcycle is most critical for the frontal surfaces of the motorcycle and rider.
29. The typical motorcycle accident allows the motorcyclist just less than 2 seconds to complete all collision avoidance action.

46. The most deadly injuries to the accident victims were injuries to the chest and head.

Keep in mind,

The Point Two air jacket inflates in less than 0.1 seconds and is designed to offer the following protection: Reduces hyperextension to the neck Provides preotection to the collarbone Neck airbag reduces helmet roll Reduces sheer load pressure to the spine
