Newey really isn't even innovating that much: he's actually more like Steve Jobs in that he recycles old ideas at the right time and perfects them. The RB hasn't been such a good car for the last 4 years because of some ingenious innovation but rather because everything fits together perfectly.Sadly, almost all of the current F1 technical directors only seem to be 'reacting' when Newey and Red Bull 'up' their game. It's a bit difficult to watch.
It's no wonder why RBR has three back-to-back titles and continues kicking everybody's a**.
If they don't get their head out and start leading with new innovation (instead of reacting), I'm afraid new engines, new regulations or anything else will not save them...and RBR will continue to lead.
