Like to mention a point about the rally drivers and going sideways discussion, a quote from WRC3's loading screen comes to mind - something like "A F1 driver see's the same corners a thousand times, a rally driver see's a thousand corners". In F1 or any circuit race its a circuit, you get practise laps, you know the track. Rallying is you and the terrain, the elements, its better go in sideways as you actually have more options. his brings me onto the iRacing video.
Why is that driver so committed? Because it's a GAME. In a game, you can have the most horrendous wipe outs and incidents pushing the limit, and its just a reset and you're back away.
I was playing Rfactor against some AI at the 60's Le Mans, and Indianapolis corner on it I tried entering the sweeping right flat and slamming on the brakes in an Audi R18. First time I misjudged it and ended up going straight on into a wall and some fence posts. In real life, you'd be seriously injured. In a game, just re start. iRacing video - one mistake in a 200mph F1 car in real life, and you're in for a big shunt and possible injury. Besides, in games they don't factor in track grip levels, wind direction, and as Mr Melancholy said, you don't have G Forces, at least simulated on the driver.
If you can do a F1 pole lap on F1 2012, well done, but doing it at 200mph with the wind in your face and the elements against you is something else. Point is GTA is finding people who can make that leap, who can make that transition.
Above is Sebastian Loeb, setting a world record at Pikes Peak. All runners got was two practise sessions, the course split in half. The ability like him to know where the car will go, judge the distance, speed, grip, is what sets true legends apart. I believe Loeb is greatest driver of this generation, but that's another discussion...
Also, we bring F1 and Rallying in about driving styles? In modern F1, cars have slicks and a lot of aero, and compared to the 80's cars like Senna's, they have tons of downforce. If you get and F1 car sideways you are 99% of the time losing time. Rallying in a 4WD 300hp road car with small downforce levels is going to be totally different.
I don't find the braking on the rumble strips to obtain oversteer realistic.
Depends though, if you have an understeering car, a moment of hitting a kerb can break traction briefly and help with a little more slip into the turn, surely? I do it on sim games sometimes, clip the kerb, naturally unsettles the car a little and free's it up? Feel free to correct me if any real world track racers are here.
