This is only really secret as it's assumed that casual players would flee from the car rather than try to destroy it, especially before the first cutscene below the bridge. For reference, you don't need to enter a cheat to see this quickly. If you gather weapons before the first mission, you'll not only be in good stead for the early parts of the game but you'll keep that "cheats activated" statistic a nice, healthy zero.

 

Aside from the lack of a cutscene, I don't think there's much more to discuss. There are plenty of tweaks missions make should you beat the criteria before it is asked of you. Sometimes dialogue will change subtly.
