Correlation does not equal causation. If the 2017 Formula 1 season happens to be a classic, be very cautious about concluding the new regulations are therefore a triumph.
If the Australian Grand Prix is a thriller, the 'success' of the new rules will be the talk of Melbourne. But it would be folly for F1 to mistake dumb luck for clever design.
The rules were predicated on a single idea: that the magic bullet for F1 was to make the cars four or five seconds per lap faster.
