Hi Deri, I am a lurker and (very) occasional poster to this list, but your comments about CP and depth perception got me interested. I have trouble with depth perception, while driving I usually under estimate the speed and distance of approaching vehicles and give way when I could safely turn across their path. I am aware of this, and because I think on coming traffic is closer than it is, I am erring on the safe side, so it isn't too serious. Where it causes trouble is on my trike when I am riding off-road. On the flat or uphill I can perceive pot holes and uneven patches in the ground fairly well. However, going downhill, with the ground falling away, the track looks smooth, I can't see potholes. Upright trikes are fairly unstable, so it doesn't take much of a pothole to flip them over, which makes riding down forest tracks at speed an interesting exercise. Can someone please explain how CP affects depth perception? I am curious about how the two relate.
