The interview does not drop any bombshells but does reflect on Alain's past passion projects (TDU 1 and 2) and reveals that despite the 1:1 map scale, tweaks and adjustments will be made to the game world to suit the types of driving and racing we all expect without getting stuck in traffic jams on very narrow roads. Alain reassures us that the game is more than just racing, but about car appreciation and enjoyment of (virtual) ownership.
