People seem not to understand the deeper problem in this

Using whatever you can in a game, is usually fine. But in theese modern days, where doing whatever to the opponent is "no problem", as long as the ref dont see it ? Where did honour & selfrespect go ?
Anyway. The main problem with using "very unrealistic tuning settings that makes no sense compared to RL physics" or whatever you wanna call it. Is, not so much that "newbs get faster".. The problem is, GT5 is not another arcade "pleassure your self in 5 min. "-game.. It's surposed to be a challenging driving simulator, which has always been mainly for gamers who take pride in "true driving". And now, as in alot of other cases, people start to feel that what they achieve, is "cool". And therefor they want to do they same, except they dont want to do the work it requires, so they use a random cheat, exploit a glitch, or go in the complete opposite way of how the game is suporsed ot work, "just because you can".
Im all in for the "people should be able to do as they see fit, as long as it doesnt hurt anybody else". But we really cant build a world, on kids who think they will get anywhere, by only having fake achievements. In Call of Duty there is people using grenade launcher to get easy no-skilled kills, to feel they are good because they are gettin alot of kills, and in GT5 people are using unrealistic tunes, picked up on the internert, so they can feel they are awesome. When they drive faster than somebody who can actually think.
So to summon up.. Gt5 is not the right game for easy/fake achievements.
And thinking "Do as little as possible, and nothing is wrong as long as you dont end up gettin locked up for it." Is just such an asocial & in the end, destructive mentality.
It still amazes me how people havent seen to understand, that the character Homer Simpson was made to be a bad example. Not your idol..
