Interesting stuff in the terrain system -
In one of the interviews Eero mentioned that he had built in a system allowing for loose surface models into Shift, and that an ideal model would be one where the tyre would be able to simulate excavating the surface it was travelling on, sink into the ground, etc. The terrain physics system looks like it has a number of references to this stuff but almost everything is set to use the same values (or ones that appear to nullify the effects) for now.
So here's plain old road surface mk1 (there are about a dozen different types of "road", then the materials for grass, berms, rumble strips, other surfaces like guardrails)
and here's grass (again several different kinds, this is the one called, er, grass):
