Firstly they were ALL cheating going off track limits, the commentators pointed it out quite correctly, but if they didn’t do it they wouldn’t be in such bumpy parts.Not to be a dick here, but that's unreasonable. Every car is over the bumps on that corner, and only one has failed. Track limits are defined on a per corner (seriously) basis by the race director for each weekend. It is not the drivers to blame. And it certainly isn't Vettels fault that his car broke - he isn't even the worst "offender" for it.
New rules won't close the performance gaps between the cars. Just makes them easier to follow. If you think this is spread out then go back to the 90s without rose tints and read the results. Cars being 2-3 laps down was completely normal.
And secondly the new rules are designed EXACTLY to make the racing much much much closer and not allow teams to stream ahead like they are, no idea why you think otherwise.. it will put a LOT of control in them and what they can do. Rightfully so, next year I only see viewing figures dropping even lower then they already have.
