The other members have laid out great explanations for the rocket vs car aero question.My only thought with respect to the V-2,was that its re-entry was of paramount concern to project designers.As a vengeance weapon,and as something to strike terror in the hearts of the British,designers were interested in the device arriving ahead of it's accoustic bow shockwave.Those on the ground would never hear it coming,terrifying indeed! The special attention to the ogival nose may have been added insurance for stealth,and may also have allowed thinner and lighter structure to the rocket,as the magnitude of the leading shockwave might allow lighter loading,something of concern for a country strapped with ever-diminishing resources.
