I never take my cards out for the very reason, but..... driving off to take some Pics from the hill requires one to actually take the camera & not leave it in the pit garage, only to drive back & be handed said camera by Cath laughing her face off

I did that at the f*&ing bike show this year. Forgot battery's, hunted down getting some new ones at the cost of a small fortune. then went back inside and got all ready\ to fire her up.

Not sure that I agree entirely with this Mike . Taking shots of bikes racing would not be considered an extreme exception , especially around here . That is where a fast lens is going to make a world of difference .
Why?
You're outside so light is generally good, so you can run a fast shutter speed without needing an aperture of F2, F4 would be perfectly OK. Also, with such a wide aperture your depth of field is so narrow it becomes hard to get really sharp focus. Remember the further away you are the longer lens you use and the narrower the depth of field. F4 at 200mm will give a depth of field of less than 30cm. If the riders shoulder is in focus, his face is out of focus. For bikes you rarely need a shutter speed much faster than 1/500sec, esp in the corners, so you can put the aperture at around F5.6-F8. On the straights it's better to use a slower shutter speed with a smaller aperture and pan with the bike to blur the background...
Here's two I prepared earlier - like 2005 MotoGP...
