While we're waiting for this, people might want to try the 'pond waves' instead, but turn the brightness right down to minimum. I've used this here in the 'circus' to simulate the ruts in the sand from the quadriga racing. Might work for some of you.

I was literally just thinking about this yesterday. Having a line tool that makes equal distant parallel lines at the very least. If not the cart wheel rut details.
