Are you able to flatten it? I have a neighbor who did this after getting a M5.
I suppose I could, thought it does beg the question why the hump is there to begin with. It's only on 1 side, so I can go around the other side with My S, but I done;t want to get into something that forces a driveway remodel if I don't have to.
That would wipe out the benefit of the tax break on the P3D-...
