At least on camera, the majority of the passing I've seen this season has been in the turns: the real stuff, the kind a driver earns. So, while getting rid of the DRS zone gimmick might reduce the number of passes on the straights, particularly in front of the grandstands, I still think there'd be a lot of passing going on this season. And, you might still see Hamilton blow by some cars in what would have been DRS zones as he works his way up to the leaders, after starting from the back of the grid or pit lane, following whatever mishap he had in qualifying that week.
