At this time of year, or any time the roads are wet, it's more the noise of the water on the roads intruding into the cabin space that seems more obvious. Not sure whether it's because the cabin on the whole is quiet, but I'm sure I've not heard it as obvious as this either in my previous Passat or cars before that.

This 'too quiet' cabin could also be why the noise from vehicles either travelling in the opposite direction, or passing by alongside, seems more intrusive as well. Anyone else noticed it?
