NFS Heat Burnout Launch Glitch

I wanted to state a very important issue that I learned today and makes the game very unfair and unrealistic also. So my friend ran into these people today and they were all drag racing and one of the kids showed him a thing called " the Burnout launch" now I know what most of you are thinking just holding L2 or R2 but that's not the only thing about it. So he stated that the guys told him to hold l2 and r2 and put your car in last gear (he was using f40 with 4.0L V8) and go to your live tuning and put drift style to brake. Then they instructed him to hold square and do not release it when you launch and it launches off like a rocket. It is very unfair and this matter needs to be taken very seriously as it is unfair for people that want to drag race and don't know how to do it. You hold R2 and L2 and hold square down and as your in last gear it launches you off like crazy. My friend said they have been doing this since payback and 2015 be for speed. Please fix this EA and please make it a important matter. Also I would like to add that a friend of mine showed me a glitch where you can make a Volvo 240 with 3.8L V8 run 8 seconds flat by messing with the parts and removing them and equipping them back on. I also have picture proof of it and if necessary I can provide it. He also had a 0 to 60 time of 1.50 which is very unfair. Stuff like this needs to be patched. Please make this game better. I love it and will continue to play it but would like these issues to be looked into.
