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.
Thanks,

Jeremy

Any landing you can walk away from is a good one.
