This is more a list of your grievances (which is fine). I would say the “basic” broken things would be things like the fact that there is no carriage in the A4’s lifetime that can allow it to achieve it’s top speed (unless you have the DLC and have mixed train themes). Or the fact that the road cargo stations in the game don’t have enough capacity to fully load a 40 ton truck. Unless these things were fixed (I know the A4’s problem is still there, I haven’t gotten to the 40 ton truck age yet).
