Very enjoyable road feel. The reflection adds to the feel nicely, especially as the road appearance isn't very dark... I was trying the 'Good and Bad Weather' mod at IoM TT before this, using 'light-rain' setting there (temp 14.5C, dusty) produced very immersive racing.
It would be awesome if the GaBW mod worked with this, having spray come off the tyres seems as much a new layer of immersion as does the feel in this mod. Cheers.
