I've never like the DRS zone aspect of F1 racing either.
Ever since racing began, winning races was based on a cars performance, and drivers skills. Cars were able to win races because of brilliant driving, and engineering, not because some particular sections of a racing circuit was chosen to allow cars to go faster by some FIA officials.
We've seen race results skewed because of the DRS factor. Watching how Lewis skillfully played the "DRS zone" against Norris for a few laps during the last race, is a perfect example. We have seen similar scenes where two team drivers have worked together using DRS zones to a competitors disadvantage and keep them at bay.
Why not let the driver himself decide where and when to use the DRS, and forget the "within one second" rule? The Indy series allows the "push to pass" at the driver's discretion, why not F1? Is it because the F1 cars have become so massive, and yet are still racing on some older historic tracks, originally designed for much smaller cars? Are DRS zones the only place a pass can still take place?
