S75D refresh owner here. Took a test drive at Austin just for kicks the other day (LR, RWD). The advisor emphatically told me M3 "took a picture" of the speed limit sign, not pulled from database as we changed roads. Would be exciting if part of it were true. Also, anybody think the fact that doors are electronically opened will lead to auto-open (or at least auto-unlatch) like the X?
