pentax is indeed rubish for sports. as one can clearly see from these examples, one cannot seriously consider pentax for sports shooting. i think most people don't understand what is really wrong: a pentax dslr is unsuitable as a speed camera. you can take some sports shots with it, sure, but that's just luck. for a speed camera on the highway, this is just unacceptable.
here are some more examples of how much rubish this is

all were shot with either a 75-150/4 smc-m or a yashica 135/2.8 (both manual focus, love them both so much that i couldn't bring myself to fit the 50-200 very capabale af lens instead
). lighting conditions: forest, cloudy day, high contrast nevertheless (typical for special stages in the forest). most are shot wide open.
i am no expert, but my humble oppinion: know your sport, and shoot with what you have. i doubt higher frame rate and smarter af will get anyone better pictures, significantly and consistently. if one shoots blind maybe that technology will get them sharper pictures, but not better overall. especially, i think there's no need to worry about it. if af is the limiting factor, you will know it right away (make sure, though, you don't mistake it for technique flaws like paning or such, it's easy to do so, i know i have). if you are "wondering" about it, than you have no issue. walk away and keep shooting
