Strange metallic shadows in low light

[Marc Collins]

Does anyone else get a strange metallic effect even on things that are not metallic (like people standing near the side of the track!) when the sun is very low/it's very low light conditions?

EDIT: It's not the shadows themselves (on the road for example), but now too late for me to fix the title!!

The reflections are overdone all the time in my opinion, but go completely bonkers as the ambient light decreases. The metallic effect is an exaggerated reflection.

I probably have the wrong settings somewhere, but was wondering if anyone else got this, or, what should I adjust to get rid of it. ALL of the rest of the textures and lighting are very pleasant except this one aspect. Very odd!
