frusterated palm, your tire explaination is kind of right. I think this is better:
A tire can never exceed 100% traction. Depending on how hard you break, you will use a certain percentage of a tires traction. Depending on how hard you accelerate, you will use a certain percentage of your tires traction. Depending on how hard you turn the wheels, you will use a certain percentage of a tires traction. If you add the percentages up, they can never exceed 100%. Its just not possible to keep traction if this happens. If they do, you will slide.
You can break very hard and try to turn slightly. You can turn very hard and try to break slightly. But you can not try to break and try to turn very hard at the same time(unless your tires are very good or your brakes are very very bad, hehe). You will exceed 100% of the tires traction. If you ever try to use over 100% of the tires traction, you will see smoke and your tires will slide.
Acceleration isnt talked about because you can rarely use 100% of your traction accelerating(except in low gears), or you are rarely accelerating hard while turning. You are usually mostly through a turn before you accelerate.
I cant remember where I read this, but I think my recollection of it is fairly accurate.
ving, youre supposed to break as late as possible while still getting a good exit from the turn. You can also think of the turn layout to plan an attack on it. If there is a lot of straight after a turn, it will be important to get a good exit. Because any mph higher you have on the exit, you will carry for the whole straight. If there isnt a lot of straight after a turn you should try to go into it as fast as possible while still not having too slow of an exit.
Basically you can go slow in, fast out. Or fast in, slow out. You should choose the way you want to do a turn based on the exhistence of a straight after the corner or not. Example, on the last turn of tokyo r246, you would definately want to go slow in fast out. If you can make an exit for that corner at 3 mph faster than another turning plan, you will be going 3mph faster for the WHOLE straight. Each second for the straight you are a faster speed at, you pull away.
