You recall that the optimal aero shape- a falling drop- has a hemisphere for a leading edge, not a bullet. That is how it is for the very subsonic speeds we operate in.

So a blunt leading edge is OK so long as the flow doesn't go turbulent as it transitions to flow along the sides.

Right. Well I meant bullet shaped / egg shaped .... you know ... anything but a flat plate like they have on that Camaro.
