Just a suggestion:

IMO It would be great to have a section which played out like the brilliant Playstation 2 series "Smugglers Run"
It would be more likely to be more arcade in control rather than the full realism, a timed event with the compass arrow showing your next pick up & drop off point so you don't rely on placing nodes.

I think it would make an excellent edition to the game and possibly make it more accessible to the casual gamer, this game deserves to be recognised more.
