Dennis got what he wanted: equality
It was later revealed of course, that McLaren had illegally obtained secret data from Nigel Stepney, which gave them that inside information regarding the floorboards, and the ability to make their case regarding the rule. The FIA, who showed incredible favoritism towards Dennis and McLaren, agreed more with McLaren's interpretation of the rule and changed the rule for the remained of the season. As a result, from that moment forward, it would have been illegal to use such a floorboard and this really affected Ferrari's performance.
It was starting to look like Dennis and McLaren were going to get away with it, but eventually his own drivers snitched on him and McLaren was punished for cheating, resulting in disqualification from the Constructor's title.
It should be noted that McLaren acknowledged their own guilt in this matter when they accepted a $100 million fine without appeal. In other words, if they felt they were innocent, they would have appealed, but they didn't. Guilty as charged!
And throughout all of this, Dennis tried to convince us all of his commitment to equality and fairness. Very few people outside of McLaren (or the UK) agreed, but I do find it ironic that at the end, Dennis got exactly what he wanted: equality.
After Kimi in his Ferrari lapped McLaren's his rookie driver, Hamilton in Brazil yesterday, both McLaren drivers ended up with 109- points each.
Imagine that? After 17 races, and all those qualifying sessions, and test sessions, the two McLaren drivers ended up equal.
Awhh, shucks... way-to-go Dennis... you really are swell!
And good for Ferrari that 109-points is 1-point less than Kimi's 110, which won Kimi the Driver's Championship to go along with Ferrari's Constructor's Championship.
