Full disclosure - I have no affiliation with this game or the designer, just thought it looked cool. All stretch goals posted have been unlocked, so I'm not even really trying to boost pledges for more loot. (though it is likely he will add a couple more stretch goals for the home stretch).
From what I gather, you really only need one maneuver deck to play...it's a bit like x-wing in that you use them to get your car from one place to another....so you pass the deck of maneuver cards to the next player when you've got your car where its going. It's just kinda nice to have one for each player...not essential.
The Passive Aggression Deck, etc. add additional upgrade options for your vehicles, again, not needed to play the game, but expand the ways in which you can hurt the other cars.
There should be enough terrain tiles in one set to play a decent sized game, from what I could see in the demo videos. although, the tiles are not needed, you could play with just the cards on your coffee table, or actually make your own detailed/flocked terrain board. The additional terrain tile sets add more/different style options for something neat looking to drive on.
This review video posted near the bottom of the kickstarter helped to sell me on it.
