Others have recommended this already. I want to bring up some visual examples here.
Would be nice to have sand, dirt, mud, snow and water puddles in Wf2. And of course mud/dirt splashing and covering up the car dynamically (and being washed off when driving through water again!). =)

The terrain deformation actually affects driving over the surface after it has been driven over once or more. Driving through deep lines/holes in the mud/snow/dirt/sand affects the handling of the car =)
I think such a feature, maybe tailored towards a 24 cars race, would fit very well with the Wreckfest games!
