Funny! Just ahead of that corner,would be the minimum pressure location on the sides of the rig,so once you pushed the door out there,the air on the interior face of the door would be at a higher pressure than the outer skin and you'd be fighting that differential.It's quite a bit of 'wing' area!
On my CRX the flow is right against the outer door surface when closed.Descending into Chama,New Mexico at 1:00 in the morning,I've kicked the driver door open and held it with my leg for air-braking.It doesn't do that much,but it helps keep me awake,and the elk love it when insane people come by in the dark.
