This is very true, and I think one of Rundstedt's points for holding the Panzers back so as to be able to consolidate and then thrust towards the landing zones. But on the flip size, the Germans were not stupid, they could work out the possible landing areas themselves. Although they had a vast stretch of coast line to defend, the defences concentrated on the key landing areas that could facilitate the landing of the vast array of materials and supplies they knew would be needed for a European invasion. That alone meant that defence went from guarding the whole coastline, to guarding areas that could handle large scale landings. But still that left a large area to be defended. Lets not forget the landing could have come anywhere on the coast of France, Norway, and the "tough old gut" of the Italian boot.
The curious thing is, the Germans had worked out correctly which possible landing zones on the French coastline the Allies were going to use: Normandy or Pas-de-Calais. The problem we have looking back on this issue is that we don't know how the armour or local defence forces such as Panzer groups would have been stationed in the area. I don't think they would have just been parked in forest or just out in the open, waiting to get bombed or pre-registered from when the navy shows up to blast them. Considering the amount of concrete being poured, the werks that were made, I could easily see some kind of bunker system, or underground werk to house local reaction panzer groups.

"He [Rommel] reported to O.K.W. on 11 June: 'The guns of most enemy warships have so powerful an effect on areas within their range that any advance into this zone dominated by fire from the sea is impossible.'" - W. Tute, J. Costello & T. Hughes, 1974, D-Day (1975 revised ed.). Pan Books. pp239.
Basically, prior to D-Day the Germans totally underestimated the effect of naval artillery and planned without giving it the consideration it deserved.
It was the advance into and through that zone that Rommel wanted to avoid. But I agree completely, of all the German Generals up to the point of the Normandy landings, Rommel was one of the few who has the experience of having seen the power of Allied Air Power and sea power. Lets not forget the Royal Navy harried the coast of North Africa. Thus why I think, Rommel had a point, driving to engage Allied forces meant exposure to Allied air power - and thus destruction even before getting to the battlefield - while Rommel wanted too, somehow, limit the time being exposed to air power before hitting the allied forces. For once engaged in close quarters, the Allies would not be so willing or so able to bring such force into action once German and Allied troops are so close, if not, intertwined.
But the argument is academic, it just didn't happen.
