I really don't mean to upset you, but are you totally serious? A replacement of a boat to van, while there is all water around it? ...How did the terrorists get to the map? By a van driving underwater? "The Mystery machine" from scooby doo :D?
And I think this change is just more of a decoration than a useful addition to the gameplay.
