The trucks come up on you so fast that a lot of times its just luck that they miss you. I used to race Ironman in Best In The Desert. The Trucks and Class 1 buggies do watch out for you but it is just luck that more quad and bikes guys arent killed IMO. If you are in the dust or making dust it is even WAY more dangerous. I race Class 10 and even we pass some of the bike and quad guys.
I am usually drunk when I post so dont take it personally !
