The Australian standard for crash barriers is about to go out for public comment. Who wishes to spend time and effort on making solid informed comments about the standard from the motorcyclist's point of view? Won't be enough to say "ick, don't like it", have to be able to give coherent reasons why something is bad. If you think you can read a standard and work out what it is on about, and see where the problems lie then let me know and I'll arrange for you to get a copy and work with others doing the same thing.
