I've kind of given up on it. I've had tonnes of submissions and none meet my standards. A few I've received just stop (like hitting a brick wall) at 407kph, one did this in 6th and just stuck, but when I changed into 7th it got faster.
The most common problem though is that the Veyron has been elevated to sheer godlike status by Top Gear and whatnot. So I'm getting submissions for cars that turn as sharply as a Caterham and accelerate to 100kph in 2 seconds.
I've driven a Veyron on the streets (albeit extremely briefly) and more importantly, I drove one on the street circuit in Adelaide prior to some GT championship deally that my buddy set up for me. And trust me, the Veyron isn't such a pleasant sensation on the track, so I'll give some pointers:
Acceleration is brutal, as you should all know by the 2.5s. However in the Australian heat there is rather a lot of lag and the car doesn't actually feel like it gets off the line much faster than my Camry. The professional driver said the same thing - the car was much slower off the line in Australia than the UK. As far as TDU is concerned - Hawaii is rather a warm environment and you would net be getting top acceleration out of a Veyron.
Cornering is (surprisingly) rather dodgy. The car is easy to drive but it is 4 wheel drive, produces a lot of downforce and it is heavy for a car of its type. If you've never seen a Veyron before. While the steering is quite sharp, it is weighted and the above factors cause a lot of understeer (or more accurately, a refusal to oversteer). It can not change direction like a flea.
From what I can gather, the higher it is, the more likely the wheels will lock up.
o.o What type of car have you got? All of mine can turn 360 degrees+ I'm fairly sure.
I get this on the default Saleen when I launch with full throttle. When launching the car, wait till "GO!" has been said and just ease on the throttle. You may also need a gauge that goes higher than 10000RPM. Not an area I'm overally experienced with.
