I've seen this raised for the xbox and playstation versions, but it's also a problem on the PC version. When riding in the passenger saloons in the ICE 3M (Koln-Aachen), the windows are dark tinted in both directions (from the inside and from the outside). This means when sitting next to the window on the inside, the outside is really dark - in real life this is not the case. It's not a huge thing, but it means that I never want to ride as a passenger as it ruins the immersion. Perhaps implementing 'one-way glass' graphics so the windows appear as normal from the inside?
This is very true, I always thought that the windows were way to dark from the inside. This also applies to the ICE 3 from Munich - Augsburg.
