It's worrying to hear that as many as six teams may have overspent during such an economically challenging time. I thinks It's more than important for the credibility of the sport that the rules are respected, and let’s just hope that the control and certification process will be done earlier than in previous years to ensure that any breaches are dealt with in a timely and credible manner.
The only way it’ll be stopped is with stricter punishments and higher financial penalties. Maybe a pre season testing ban for next season and a -30 constructors points deduction. Red Bull’s penalty was laughable last year and made no difference to them whatsoever. That’s not a punishment and when you consider the astronomical penalty McLaren got back in 2007 for a rogue employee and no credible evidence data was even used in the design of the car, the FIA need to define a set of punishments that are consistent. If the penalty for breaching the cap is basically what Red Bull got last year, I think most of the bigger teams will see it as a manageable risk.
