One point of the DARPA challenge (cited earlier in this thread) is to
create autonomous vehicles capable of simply getting from point A to
B in a dynamic environment. The results speak for themselves.


They do - and what they tell us is that navigating over uncharted
terrain, full of obstacles, is a challenge for land vehicles.

Apparently, you missed the part where most of the vehicles also failed the
"charted" course. In other words, they failed because they were not
capable of functioning autonomously. Regardless of the notions, acting
autonomously in a 2D dynamic environment will always be easier than
operating in a 3D dynamic environment. It really is a problem based in the
limitations of AI; we aren't there yet.
