Why do they do this?

Watching the scFi channel's "War of the Worlds". Nice to see that they realized three-legged walkers are unstable and way too easy too take out. Six legs works.

But having done that, what *idiot* decided that the legs should be *pointed*. Those legs should be sinking *feet* into the ground. And at least inches into concrete and blacktop.

This is not rocket science folks.
