Just need more contrast.

Try upping the light.
Try #default{finish{ambient 0}}.
Try sphere{CamLoc,.0001 pigment{rgbt <.5.5.5,2>}}
Try dimming whatever fill light is lighting your shadows

The traces left by the wheels are missing! Where is the shadow under the buggy?
You may have to much ambient, try something less than the default of 0.1.
A low value for the assumed_gamma can wash out contrasts and shadows, try 1 or a
little more.

Scenes in direct sunlight have very harsh and rather dark shadows. These
will add contrast to your scene. Light the scene by one strong light and
maybe a weak fill at some places. Also, make sure to use a slightly
yelowish light instead of pure white.

   I haven't got that far yet!  ;)

  Btw, you do know that this buggy is about 3 feet off the ground?


> Where is the shadow under the buggy?

  It's there, but contrasted out of all recognition. Washed out, in other 
words...  :o/

   Playing around with this right now. Thanks.

     Yes, definately.

     That last one is the problem, I think. Thanks Shay, I'm playing around 
with these right now, but what does that CamLoc thing literally do?

   You've done this Marc? That's cool. I'd love a go at it, not as a serious 
sporting hobby, but a quick ten minute sprint down a loooong clear beach 
would be fun - that would do me for life, I think...  ;)

 When you say a 'sidewind', do you mean at an angle of around 22 degrees? 
This would make sense to me.

  Another thing; are you guys strapped in at all? From the images I found on 
Google, I couldn't make out if they were strapped in or not.

     I'm giving this a go right now.

    And this too. Thanks.

'CamLoc' was just my abbreviation for Camera Location. The contrast of a 
scene can be strengthened by adding a small sphere around the camera 
with a gray color and transmit > 1. I think Rune was the first to try this.

I didn't sail a kite buggy but I used to sail slalom/speed windsurfing and
speedsail (big skateboard with a sail as on a windsurf)

I mean close to 90 degrees (upwind tack) because there is only few
resistance and relative wind due to speed make you feel upwind while you are
actually crosswind.
