My question is this:

Water has a lubricating effect. If the road is wet, but not wet enough for water to actually stand on the surface, needing to be moved, does this mitigate losses in FE due to rain?

I would think it would actually increase FE in this scenario, since water has the lubrication effect, which would reduce frictional losses between the tires and the road.

Thoughts?
