Seeing the ammount of people that jump to defend this CSA is quite alarming and tells a sad story about the future of GTS. And here's why:
First, let's deal with the technical aspects of CSA. Unlike all other aides in this game (TC, ABS, ASM), this aid does NOT exist in real life - it actually only exist in competitions for R/C cars, curiously, bot that has nothing to do with motorsport. So ok, it's not real, but what's the issue with it? GT games have always prided themselves as being "Real" simulators, and at the very least a good tool to get the hang of driving fast, learning something from it. GTS, indeed, has fallen a bit behind as far as physics go, when compared to the likes of Assetto Corsa or iRacing (PC2 is not realistic as many people THINK, but that's a different conversation) - however they have been improving things in the latest patches, which is nice, I'm enjoying the realistic physics more with each patch.
The issue with CSA is actually just lies in one instance - the daily/championship races , or rather only the Championship races. These FIA approved online championships should be 100% about competition, driver skill, etc because there's also a REAL prize at stake. CSA basically counter steers for you - and that's a huge problem, because in real life racing, the biggest enemy of any driver is his lack of attention and fast reflexes in key moments throught a race. Many, many times a result of a race is determined by how good and consistend is one driver vs another. And with CSA, it's really hugely more difficult to spin out than without it. This creates 2 problems: 1) As far as the nature of GTS goes, this is a completely unrealistic aid that does not exist in real life, and 2) Creates an unfair advantage for some people in FIA championships, because it renders them immune to mistakes.
You might say that ANYONE can turn it on. True. But I don't know about you - i love sim racing, and I love getting as much realism out of them as possible, and even though, of course GTS is not perfect (no sim game is) - CSA takes a huge bite out of any semblence of reality and makes the cars behave very very weird - almost NFS territory weird - because it holds your hand and automatically applies counter steer for you. This makes many racers not want to use it because we want authentic feel for the game we bought - and gives an unfair advantage to many gamers. These gamers not only get an advantage by throwing the car around mercilessly without the risk of spinning out - but they're also missing out on fine-tuning their counter steering skill and a better feel about their newly achieved level of driving.
People talking about other aides, like TC and ABS for instance, at least as far as (real-life) GT4, GT3, GT300, GTE, SpuerGT500 and LMP 1 & 2 cars (some of these categories are equivalent to Gr4, Gr3 and Gr1), TC and ABS are both allowed. TC does NOT give you an unfair advantage because unless you learn to finely tether the throttle of a car, you will never exist out of a corner with TC on vs TC off - but there's a risk of spinning out untill you harness that skill. And ABS off - technically you can stop much faster with it off, or at least to Weak (i use it and I can confirm it) - but you do need to modulate it quite well in order to make sure you don't end up locking the tires and going into the bushes. (ABS off is WAY too hard core for me in GTS - in PC2 for instance it feels like ABS Weak in GTS).
A solution for this problem should be presented by Polyphony. the very existence of CSA in FIA online championships is really weird. They should address that, I consider. And what they could do, is an option similar to PC2 - Aides set on "Authentic". This way each cars will only have their realistic analogue aides available. That means for instance nu ABS for the Ferrari F40. It's really annoying at the moment that you have to set the ABS level before starting a race. In GT racing in real life, you can adjust the ABS on the fly, like you can do the TC, Fuel Map, Break Balance, etc in GTS. They should change that.
Anyway, that's my "TL
