What is ESP in cars?

I often mention ESP in my posts but never describe or explain what it is.

ESP supports drivers in almost all critical driving situations. It detects skidding in an instant and counteracts it. ESP works both in the event of over steer and under steer, and when avoiding obstacles.

ESP's life saving potential has been confirmed by many studies in America, Germany, by Daimler-Benz, Toyota, VW and Renault.

ESP will be fitted as standard in cars as of the end 2011. Meanwhile, it's best not to buy a vehicle without it. Road holding and braking are vital for active safety and accident avoidance.

You'll find ESP is fitted as standard to most new models. For example the new Mitsubishi ASX and Kia Sportage have ESP fitted as standard. Thinking about it nearly all SUVs have it fitted. I think the Yeti is the only odd-one-out.
