    The primary focus of this specific topic area is the implementation of cameras. Proposals may contain additional solutions so long as the cameras are used as detailed in the topic.

  2. It’s noted that NHTSA, FHA, FAA, etc. have had success with similar systems. Why haven’t these systems been adapted for this use case?
