The regolith/field is the stuff used in shower walls. The plastic slightly textured I think. The rover wheels have less traction than the field itself. This was done most likely for safety and it's cheaper. Yes the field is slippery. Last year when our robot would be going at top speed and turned sharply, we'd slip. We had two wide rubber drive wheels are 2 cheap-o in line casters.
