Another fascinating subject Han - super-quick guys like Evgeniy using fairly old tech, and the rest of the spectrum from the best/worst gear, fastest/slowest drivers.
I sometimes wonder if it's something to do with what we're used to - I'm forever searching for the feeling I had when driving quick cars 40+ yrs ago, whereas someone used to gaming might require, or have, different ways of reacting to input/feedback... I guess there's many other 'examples too; for example someone who's got many years of driving games/sims experience (including setup idiosyncrasies between real and virtual cars), and not much actual road driving. Certainly not saying any are better or worse, just different.
Having tried some decent pedals (they were hydraulic) I'm looking to upgrade asap, for what I want out of sims they seemed ideal - gave me more speed, but in particular, much better consistency. Only a year to wait
I think you're right, I learned to drive quickly in a Caterham-esque kit car on trackdays and driving sims has made me realise that to push hard I rely quite heavily on knowing what the back end of the car is doing through my bum as much as anything, something you obviously you can't get from a sim at least not without a motion rig that can simulate yaw. Likewise braking, I find it difficult to judge if I'm braking at the limit from visual and audible cues alone because I'm used to judging it primarily from the feeling of retardation pushing me forwards on the belts etc.
Conversely if all you've ever done is drive fast on a sim then your brain has never had those extra real-life inputs to make use of so it probably adapts better to interpreting the visual and wheel feedback information it's given via the sim. Like anything I guess with time and experience your brain adapts (and I'm certainly a lot better now than I was a month ago when I first built my new gaming rig and dusted off the wheel) but I'm not sure I'll ever really drive as natually on a sim as I can in real life until it can replicate the same feeling of motion and rotation.
