Do you have it? Do you use it? Can you develop it? Is it a crock or is it common sense and experience combined to set a little alarm off in your head that says "extra caution required here"? I noticed a LED signboard on an overpass on the SE freeway on the way into Brisbane that said "Develop your sixth sense" It had more but I was in traffic concentrating on what was going on around me. It had a rather large bike and rider picture in it, so there was no mistake it is aimed at bike riders. Maybe they've given up on car drivers looking out for bikes and now putting the onus on the bike rider.
