^i'd say the large majority aren't shooting with protective filters in those conditions...
From the rodeos I shoot at, I'd say you are wrong. Most if not all photogs, at least the professionals, are using filters. Not only does the filter protect the lens from flying rocks, but they also allow easy cleaning by just removing the filter and putting another on. And yes, the filters are very dirty with dust and mud stuck onto them. If you were to clean a lens with that much debri stuck on, you would be at it for at least 5 minutes...wasting time and valuable shots.
I think the people that don't use filters are weekend warriors out in the park taking nice photos of their family where I agree, who needs filters in these cases. But there are sure conditions under which I would not shoot without a filter. I'd even have a plexiglass face mask if I could still use the viewfinder as I've been dinged by many a flying rock which could easily damage a tooth or eye.
