I'll always say that complaining about racing being 'artificial' doesn't make sense. It's not like F1 cars grow in the wild: the entire enterprise is artificial. Further, as a spectator sport, the rules should always adjust towards making a watchable product (even if the powers that be get that wrong, I'll give them a pass on good faith attempts).
With that said... I don't care for the push to pass system where a car has reserve power they're only allowed to deploy a fixed amount of time. I'm fine with DRS, and I like, as a spectator, that there's a way to give an advantage to a trailing car that is still a technical innovation (doesn't everyone say that RBR has a better DRS than others? Another area to differentiate the cars is about as un 'artificial' as F1 gets isn't it?). I've enjoyed the last couple of seasons with drivers using detection points and multiple DRS zones strategically, appearing to lose a place only to actually solidify it half a lap later.
I like the current DRS system, though if someone wants to tinker, I'll be open minded. I don't want the cars to be 'artificially' limited (I'm already not a fan of rev limiters and a cap on ERS deployment). In a cost cap era let someone blow up their engine if they want. And if F1 wants to be at the forefront of automotive technology, the hybrid system should be unlimited. Left to their own devices, an F1 team might be able to come up with a car that is basically electric, using the ICE as power boost.
