Not pass in a corner? I'm sorry that is complete and utter bull****. The person in front should be defending their spot. And once your past the a-pillar its up to the driver behind them to give way.
I did not say, "Don't pass in a corner." I meant that it is not always
best to pass in a corner if it sets you up with a disadvantage into the next corner.
Many races have been won by drivers seeing that they have an advantage and can successfully make the pass in a corner. The downside is that the other driver may have you in his blindspot and will knock you off course. Worse than that, your aggressiveness may knock him off course and ruin his race. That's just selfish. We have all seen the bumper car contests that some of these races turn into. In any type of racing, situational awareness is the responsibility of the driver attempting to pass. If the driver attempting to pass in another car's blind spot causes the contact, he must also suffer the consequences. Everyone is racing for fun. It's the discourteous drivers that cause all the problems. You just have to
try to be patient and
try to be a sportsman. I for one have ruined many a person's chances at a checkered flag through my own impatience. I believe we all have at some point. It is important not to upset the driver who clearly "owns" the line.
In some sims (and certainly in the real world) your suspension and tires may be significantly damaged by making contact. You can see where I am going from here...and don't forget, GT5 should have some kind of damage modeling. However, it remains to be seen whether or not it will portray cosmetic or some kind of "realistic" suspension type damage.
However, if you can make a clean pass, by all means, capitalize on it. That's racing.
For your birthday I think you should ask for a dictionary and look up the meaning of rant.
rant
v. rant·ed, rant·ing, rants
v. intr.
To speak or write in an angry or violent manner; rave.
v. tr.
To utter or express with violence or extravagance: a dictator who ranted his vitriol onto a captive audience.
n.
1. Violent or extravagant speech or writing.
2. A speech or piece of writing that incites anger or violence: "The vast majority [of teenagers logged onto the Internet] did not encounter recipes for pipe bombs or deranged rants about white supremacy" (Daniel Okrent).
3. Chiefly British Wild or uproarious merriment.
Wow!!! I've been had! 
I am investing in a dictionary ASAP.
Sounds like many people in this thread want to learn more.
I'd recommend
1. Going Faster - Skip Barber Racing School.
2. The Speed Secrets series - 3 books. 1st book is the best.
They are all available on Amazon.com etc, and well worth it if you're interested in.... going faster.
That is some great advice.
I am not hyping LFS. This is the GT5 forum and I love this game. However, for the sake of a demonstration of good etiquette, this video says it all. Fast forward a bit into it and you will see some good clean online racing.

Here is some good advice for those interested in online racing etiquette.
http://en.lfsmanual.net/wiki/Clean_Racers_Club_Rules
It comes from the
Live For Speed online manual. Not all of it will apply to GT5
, but much of it will be helpful in many circumstances. Furthermore, if you type in "Sim racing etiquette" in a search engine, you will be linked to a number of sites that post a number of racing organization's rules about passing, vehicular contact, etc. You will see that most everyone agrees on basic courtesies in the racing environment. It's really just basic common sense stuff but there is almost always some information that may be new and beneficial to those who are interested.
I will state straight way that there are almost no rules short of the sometimes faulty penalty in GT5. In no way is anyone expected to follow any type rules when racing online and I am not trying to steer GT5 into the hardcore sim category. That would not be fun for everyone and I have no problem with that. Some of the points I provided below are meant to only enhance the online enjoyment of racers that agree to follow any commonly agreed upon rules. You just have to decide for yourself whether or not you want to be a good sportsman or a winner at all costs.
Here are just a few examples:
(Corner rights rules are generally straight forward in any sim type game)
Corner Rights
CR-1: You must establish substantial overlap with the car ahead before they reach the corners turn-in point to have the right to drive up their inside, or to expect them to leave inside room for you. Substantial overlap means at least that the front of your car is up to say the drivers position in the ahead car - and thats at the very least. You probably should have more overlap in some circumstances. The ahead driver has the right to be fully committed to the racing line of their choice without any interference if there was no substantial overlap before he turned in.
CR-2: If sufficient overlap is established before the turn-in point, then the behind driver has the right to sufficient side room. The ahead driver must then leave sufficient side room for the behind driver.
CR-2A: The car on the outside has the right to outside room all the way through the corner right up to the exit point. They should not be squeezed against the outside towards the exit point.
CR-2B: The car on the inside has the right to inside room all the way through the corner - right up to the exit point. They should not be squeezed against the inside towards the apex area. The ahead driver can still battle for the position of course but must do so while maintaining side room for the behind driver. The practice of going up the inside of an ahead car after they have already turned in, and where there was no established substantial overlap before the turn-in point, is sometimes referred to as barge passing, ( I.e. you barge your way past ). Understand that barge passing is a high risk manoeuvre for both you and others. You have no rights what-so-ever as a barge passer. Should you cause an accident from a barge passing manoeuvre youll be in a defenceless position should you be protested?
CR-3: Where an ahead driver has clearly made a sufficient error to warrant a passing move a behind driver may attack their position, with due caution and care, regardless of whether there was any pre-existing overlap. E.g. - If the ahead driver brakes too late and drifts out wide of the apex and then has to reduce speed etc. This would be a valid passing opportunity regardless of whether there was pre-existing overlap. However, there is still substantial responsibility on the overtaking driver to take all necessary care to avoid contact. Small errors by the ahead driver may not be sufficient to justify an attacking passing move however. Just because the ahead drivers gets a bit out of shape at times doesnt give you an automatic right to pass uncontested by them or a right to room. You still have to judge if their error provides sufficient opportunity for a safe pass to take place.
Defensive Driving
DD-1: Leading cars have the right to choose their own line down a straight. They may make one move to block an attacking car to protect their position while on a straight - but then must maintain that position as long as the attacker remains affected by their position. Then, naturally, as they approach the next corner, they can of course return to the racing line of their choice for the corner.
DD-2: Leading cars have the right to take their line of choice through corners. E.G. they may drive a defensive line around the inside of a corner to protect their position, thereby forcing an attacking driver to try to pass around the outside. This is not blocking and is part of normal racing etiquette.
Like I stated earlier, there are no rules in GT5 and I really don't expect to see many people racing as fairly in the average online race. They are just more tools to put in your toolbox and can easily be implemented if GT5 eventually offers private server rooms.
). I hope to see others racers from GT planet online (please wave when you pass me!
