I remember a guy who crashed at the nordschleife (first ever real world lap for him) and told the marshals: "It had worked on GT"
What really helps is to learn a new track (NOT Braking points etc)
As someone who visits the track regularly, I'll tell you. No, it won't help you're driving. It WILL help you memorise a track if the track is modelled correctly, but it won't help you drive.
Bingo.
I actually went to the Nürburgring in 2005 with my father. We opted to skip the 'Ring Taxi experience and I drove laps in a rental car, having never actually been on the track before. It was all perfectly fine for two reasons:
- Even though GT4 only released in February of that year (I went to the 'Ring in June) I had actually been lapping a virtual Nordschleife for many more months before that, on Project Gotham Racing 2. Inaccurate as that version was, it taught me all the corners, and it only took a small amount of time with GT4 to adjust to the "real" layout of the track.
- My father -- no doubt wondering why he ever agreed to not only let his 18-year-old son take a rental car on laps around a racetrack he had never seen before, but also ride along -- squawked "SLOW DOWN!" uncontrollably any time I began brushing 90mph, regardless of the straightness/curviness of the road ahead. He wasn't angry at all, but he was certainly a reluctant passenger.

The funny thing is that I
hate GT4, but while we toured the museums before doing our laps, they had a room with a whole bunch of PS2s and GT4 set up; my father jokingly suggested I "practice" first on the wheel-and-pedal sim rig. Nervous that the hyper-sensitive snap-overcorrection in the game's physics would catch me up and turn him off from our plans, and knowing I wouldn't really enjoy the lap, I reluctantly agreed. Fortunately, I was able to casually demonstrate my knowledge of the corners in a lap with the BMW M3 GTR (race version), with no crashes or offs. My dad admitted he felt better about the whole thing after that.
Even with the "paternal brake" firmly engaged, we (roughly) timed my lap to be about 12 minutes, which I was content with, all things considered. I was mainly hampered on the straighter sections; though I only engaged ABS once on the damp track, I was pushing that 525i touring pretty hard. I only wish they'd had a smaller BMW available (we chose the 5er to avoid a ForTwo or VW Polo), or that the car had a manual transmission. Next time...
If anyone's interested, the original GTPlanet thread where I detailed my experience
can be found here. (Warning: Teenaged emoticon overload. Boy, did I write differently back then...)
----------------------------
Getting back to the point of the thread, I didn't have a great time at the Nürburgring because Gran Turismo taught me how to drive there (in fact, it helped that I
despised GT4's physics and didn't trust them one bit). I had a great time at the Nürburgring because Gran Turismo
taught me what all of the corners looked like.
The
only racing simulator I've tried that has "made" any tangible improvement upon my driving skill (and the only one I think could really help anyone else) is Live for Speed for the PC. Everything else is too grippy, too vague, too "sterile," and often just plain inaccurate. Yet even in LFS, you don't "learn how to drive" because you can drive in the game. It merely helps you practice what you already know or can learn elsewhere.
At its very best, a proper, realistic sim is a
tool. Not a "teacher."
I feel I should also note that while Gran Turismo 5 is a pretty good sim, it's still pretty far from the level of "properly realistic." Don't try this at home, kids. If you must, do what I suggest below:
RWD 335i. I'm not a total noob a few times the back has stepped out and I saved it, im talking about the controlled drifts, where you want the back end to go out and control it through a curve.
Like
BigYoSpeck told you, a well-worn tradition among RWD drivers is to take the car to an
empty parking lot on a wet or snowy day and have at it. The reduced traction makes it easier to get what you want, and at much slower (safer) speeds. As a bonus, at least in my area, the most hassle you'll get from any authorities is a "hey, you can't do that. Move along." Maybe not so much on a rainy day, but certainly in snow. As long as you comply and leave, there won't be any trouble. 👍
