If the DLC is released on the day the game is released, that means that the DLC was ready and could have been placed within the main game disk itself.

I remember a time when you played a game and was rewarded with new cars, colors, characters ect after you compleated the game. Now adays this is all sold as DLC. 

Except the games need to be mass produced and distributed to retailers, which takes a few weeks.
You really think a new weapon, costume or car can't be created in that time ?
