Where can I learn for free online how to race cars properly?

A better game is Gran Turismo 3 or 4. The computer will show you when to brake, has a traction control system, and is pretty realistic. It will take a ton of practice and adjusting the car to get "the feel". Once you get pretty good at Gran Turismo other racing games become easier. Racing cars well takes a basic understanding of physics and car control, even in a video game. Keep working at it and adjusting on the car. After a while, it will become easier. Be careful, it is easy to take a good handling car and ruin it! If you are interested, Carrol Smith has books on racing and driving called Prepare to Win, Engineer to Win, Tune to win, and Drive to Win. Look around on the internet and you will be able to buy them. I think Amazon.com has them. Or try Skip Barber Racing School's website. I think they have a driving book, also. Practice, Practice, Practice. Good Luck.

Practice, Practice, Practice. Good game though.

Well really on a game all you can do is keep doing it. That's how I learn every time and that's kind of what you're supposed to do anyways. Oh yeah and in real life if you got the guts and the ability then you wouldn't need help. There really is no secret just don't fear death
