I agree with you (and others) about this. Yet, Nikon, Canon, and Sony gave their pro models a high frame count for some reason. They have crazy ciné-like speeds. Maybe I'm wrong assuming professionals were the target customer of that feature.
Yes, I've thought about this as well. And I can only respond to it based on experience. When I see a live press conference where the press cameras are permitted, you always hear a flurry of motor drive activity whenever the speaker makes an overt movement. So these newspaper guys are after that -- movement and the possibility of an interesting expression while the movement is taking place. So a fast motor drive is good for this sort of thing. Also, in field sports such as both American and International Football, where action can be fast paced and often confusing, again, a fast motor drive can be useful for freezing interesting moments where it might be difficult to find the exact "best moment."
But motorsports seldom requires the fast pace of a motor drive, I've found. There's a fair amount of waiting and anticipation. An exception might be an accident a photographer would want to capture in detail. But other than that, I can't really think of much reason to use the rapid fire of a motor drive at all . . . Although I can think of one recent exception. I was shooting with my Sony NEX 7 and a manual focus Tamron 300/2.8 at a motorcycle race. I had positioned myself at the end of the longest straight on the course right at a tight turn. This caused all the riders to bunch up tightly. I know from previous experience in situations like this to prefocus on a specific part of the track, so that's what I did. But I wanted to catch as much of the action during this flurry as I could so, probably for only the second or third time in my life, I used a motordrive on Continuous setting. The NEX's motor drive, in this cas -- and not just any one, but the high speed one that forsakes focus -- like 10 or 11 fps. So when those bikes hit the spot I'd focused on - Bzzzzzz. It worked -- I got several keepers from that one press of the shutter release. That technique worked best at the beginning of the race, when all the riders are still tightly bunched up, I found.
Here's a shot from that race, show you what I mean:

Wonderful car photos.
Thanks. I'd like to see some of yours. Got any links you'd care to share?
