I honestly dont see why people are so up in arms about this paddle system, Ferrari do almost exactly the same thing, as do Reanult, BMW, Honda, Toyota, RBR, STR, FIF1 & Williams (and even Super Aguri lol) except they all use a dial on the steering wheel to change engine maps whereas Mclaren have chosen to use paddles. Initially I thought I'd completly misunderstood the idea and that it wasn't simply a "paddle-switch-insted-of-a-button-or-dial-switch" but reading this thread its clear that in fact that is the case.
Whats the big deal? Its not a form of TC, it is there to improve the driveability of the car leaving corners in various gears (and at the start), hence it is used (and has been used for years) by all the teams on the grid, thus not only is it completely legal but it is also not against the spirit of the rules either (seeing as the "dials-on-the-steering-wheel" version of this has been used for years by all teams without complaint from eachother). If it really was an atempt to reproduce a form of TC after the Ban you can bet your last pound/dollar/euro (etc. lol) that the other teams would be making a right noise about it.
But all's quiet on the western front so far.
Personally I see it as an ingenius idea, in that it is brilliant in its simplicity. Schumi was brilliant to watch on the onboard shots in his Ferrari, sometimes it was like he couldn't sit still (getting bored on his way to another dominating drive maybe? LOL!) because he was almost continually playing and fiddling with brake bias, TC settings, engine maps, engine braking setiings the whole lot. I bet he'd have appriciated a system like this. (Or maybe it would have taken away something to preoccupy himself with while out in front lol!)
I don't think it should be banned, cause I dont think they are getting an unfair advnatage, somebodty already said Renault were running this in 2006, and I wouldn't be suprised if somebody else is trialing the idea in their car, but if it were banned (say the FIA decided to implement a rule saying that they should have only one engine map) I dont think it would really change the "pecking order" so to speak, Ferrari, Mclaren & BMW would still be the top 3, and Honda will still be wondering what on god green earth (no pun intended) is going wrong with their car.
Silence is golden when you don't know a good answer.
