I never really did play TSW much until ECW came out. Then I've spent quite a while driving different routes with different traction. When I first played ECW when it as launched, I noticed the sun was reflecting on the inside of the windscreen when the sun was directly behind, which I thought was odd but maybe was just a TSW thing. But it definitely seems to be a bug with ECW / The 377 though. See the screenshots below. No way would the sun be reflecting off the inside of the windscreen at that angle.
