Barbed wire slows tracked vehicles down, the more the density then the more it gets slowed down (and it can possibly stick on it). Barbed wire entanglements got wrapped round the drive sprockets and stopped tanks from WW1 onwards. Allied tankers hated vineyards in Italy since the unbarbed wire used in these did the same thing.

I'd wait for the engineers to clear it (or go around) myself if it is more than say 1 strand dense. I would only crash through if I really had to.

Pavement overrides trees sometimes, it depends on the map generation. Pavement is one of those features that can occasionally do strange things.

Dragons teeth provide no cover.

The movement highlight is merely an estimate, it cannot be guaranteed 100%, and is completely fooled by water and vehicles with both swim and land movement. It always has been, though we fixed some of it 5 or so years ago or more. (I never use the feature myself - one of the first options I switched of in SP1 when I got my copy, never used since).
