Only a few comments were received regarding the total system. One comment was that the system
was complex, with a large number of components. As a result, there is a need to consider the
potential for false warnings and for risks if some components fail. Another comment was that there
should be fewer adaptation thresholds (reflecting this reviewer’s comments on specific subsystems).
Another noted that there should be consideration of whether the prototype interfaces are allowable
under the Federal Motor Vehicle Safety Standards (FMVSS) or other regulations and voluntary
agreements.
