years and years ago (1990s) I used to do autocross (then called gymkana) with may 1967 Chevelle SS. All the guys with hondas a BMWs thought I was insane for pusing a 2 ton detroit land yacht through the cones as hard as I did, but it was good practice.
It also showed me there are two types of performance drivers, drivers who drive by feel, and drivers who drive by the book. A by the book driver can look at curve and see the braking marker for every turn, know exactly when to power in, their technique is flawless and they can do repeat their performance reguardless of G -force. They tend to be on the conservative side. Drivers who drive by feel typically push their vehicle a lot harder and take a greater number of chances. They can feel the slightest variation of traction in their fingertips and are extremely adaptive, and they have faith in their skill. Overall Their technique is poor but their reflexes are fast and they can usually cover up mistakes with a lit of minute changes. They are the drivers who make the most improvement though practice. Great race drivers are usually a combination of both but start out as one or the other and have to learn the rest through trial and error.
Two years ago I went out to an arcade (dave and busters) with some subaru WRX enthuasists. There was this ferrari racing game and we all had a chance at it. The drivers who were by the book were setting low lap times and banging the high score right off the bat, the drivers who drive by feel (like me) were spinning that VR f355 off in the first turn every time, although after about $5 worth of seat time a piece we were cracking into the high score board. On the way out we decided to fuck around on some freeway clover leafs (on/off ramps) and those same guys who were banging the high score board were mortified when I passed their 'rexes and STi's a couple of times adound the clover leaf...full lock....4 wheel drifting...in a 1967 GTO...on bias ply tires with 14" rims.
Keep at it, I fully believe that there is a lot to learn about your own driving and riding technique from realistic driving games.
