Straps, lights... last barrier
Thanks to those responding to my original post.
The straps are suggested due to the past studies of lights appearing to be 'inappropriate' for a variety of reasons - see excellent 31 Aug posts.
My preference of course would be a means of turning the green lights to red. However, that is a major modification taking years to establish...
... meantime, straps are something that could happen almost immediately if someone was bold enough to act on a practical, cost effective, pilot supported proposal.
We'd like to hear any comments, especially if there are any flaws to the idea.
