Cost of the air bag system will be kept within Vision saves as bounds and designs will be tailored to various automakers' needs. Scenarios 1. The systems engineering team (SET) will review all safety regulations published by the National Highway Traffic Safety Administration (NHTSA), send questions and comments to NHTSA on a timely basis, receive responses, and incorporate these regulations into the air bag design. systems, formulate questions and comments to the research teams on a design is consistent with the best research available. the manufacturing system for the air bag system to the appropriate 2.
