It has everything to do with avoidance manuevers
It has nothing to do with avoidance maneuvers. If at any time the front or rear of the car is not going in the direction of the steering wheel ESC will kick in. There are various reasons skid could occur or could be about to occur that are not due to avoidance. Stupid driving in slick conditions is one example that comes to mind.

It will kick in on ice and snow but its effectiveness is limited on those types of surfaces.
As noted, ESC can't manufacture traction or go beyond physics. It's another safety device, of which stupidity can negate it's effectiveness.

When you make an emergency lane change the potential exists for oversteer - the rear of the vehicle starts to slide out - which is usually followed by an overcorrection causing the vehicle to fishtail and possibly to spin out. ESC will absolutely, positively correct the oversteer and prevent fishtailing and loss of control. It doesn't have to be a slick surface to cause understeer or oversteer.
Go here and click on the 1.5 minute video on the right hand side. Almost every demonstration of ESC includes an emergency lane change.

akirby, you keep missing the point. It's not about emergency manuevers. It's about keeping the car going in the same direction as the front wheels are pointed. Oversteer, understeer whatever.
I'll repeat, one does not have to make an emergency manuever to have ESC kick in. I have some knowledge about ESC systems as my former car had one. ESC would kick in to keep the car from sliding or to stop the wheels from spinning.

You guys are basically saying the same thing but are hung up on grammatics. Anytime I feel any slippage I am going to react and perform some sort of "avoidance or emergency manuever". It doesn't have to involve an emergency lane change.

ESC will help you control the car, regardless. It could be from an avoidance maneuver, or not. Any time the wheels loose traction, ESC will take action to stop it.
ESC, and all the other safety features have their value, and help reduce accidents. That's great! The question I have is, when is it too much. ESC, ABS, Airbags, Seatbelt tensioners, lane change sensors, crumple zones, etc, etc,. All these safety features are adding to the price of our cars, so where do we draw the line? When the safety features cost more than the rest of the car? We may be close to that point now.

That point came long ago, when cars were first invented actually, since the most important safety feature of any car is the human brain--the value of which is priceless.
But that aside, I'd rather pay more for all the latest safety features than for stuff I don't need like nav systems, 100 gigawatt sound systems with disk arrays, DVDs, etc. etc.

But you said it had "nothing to do with emergency maneuvers" and that's not true. I never said that was the ONLY time ESC kicked in. It will definitely kick in whenever the car begins to understeer or oversteer including slippery conditions.
However, it doesn't stop wheelspin - that's traction control and while TC is almost always included with ESC you can get TC without ESC in some vehicles.

I can agree with you on the things I don't want or need, like nav systems, mega sound systems, etc. But will the price for safety ever be too much for you backy? Should every safety feature be mandated by the government? Do you need a sensor to tell you when you've gone over some line on the road? If my car goes off the road, or into the other lane, I will know about it. I don't need to pay for some gadget to tell me that.

I'm more interested in help in staying on my side of the road vs. being told that I've crossed over the line to the other side. I don't think any car in this class has such a device anyway, does it?
