That makes sense for Germany, but the US does not have universally good roads or reasonably trained drivers. Many states have no regular vehicle safety inspection. On top of all that, culturally, the US is just very different when it comes to respecting regulation. I have seen germans completely befuddled when they realize that Americans will intentionally ignore laws and regulations. To many Germans it seems like it is almost inconceivable that otherwise respectable people will just not follow rules sometimes.
