Marshals just have to be alert, you cant complain if they are trying their best. At a small track there are times when its never properly 'safe' to jump onto the track.
Also the amount of drivers that spin the wheels etc is unforgivable, just leave the cars there until they stop it. If a driver spins the wheels if you are holding the car you should put it off the track, loosing a race is perfectly fair against someone trying to injure you.
