Typically, when I've read about the test usually done to measure grip, a common one mentioned is a 200-300ft skidpad. That's essentially a circle with a 200-300ft diameter in which they negotiate the circle a number of times while keeping the car over the centerline of the circle and then they calculate the result. This is most commonly the figure you'll see in magazines and such. It's unlikely most cars are going to be doing a 200-300ft skidpad at 100mph.

Here's an article from MotorTrend magazine describing their testing procedures, in which they mention the skidpad, as well as their own figure 8 testing.

Car and Driver also did an article in which they spoke about their skidpad testing and how it's done (along with tables showing some of their best results from the 1970's through 2008, when the article was published): https://www.caranddriver.com/features/rocket-sleds-the-best-performers-from-50-years-of-car-and-driver-testing-orbitals-page-3
