If I understand what you mean by "trap-focus," this is a feature on the 1V. That is a custom function you can set to take the picture when a pre- selected point comes in focus. As to why it's not included on more cameras, I can only speculate. One reason would be that autofocus speeds have increase to the point that it is not necessary in most cases. Another reason would be the speed of the "motor drives." With even inexpensive cameras being able to shoot at almost 3 fps, it is seldom necessary to have a "get the right timing or miss the shot" incident. Especially in a case such as a jeep coming over a dune. One could preselect the focus then start firing before and keep firing until the Jeep passes. Just my 2 cents.
