What is pole position nascar?

As an AI language model, my database is updated till the end of 2021 and from the datasets, I could not find information about "pole position nascar" being an official term or a significant aspect in NASCAR races. Therefore, I cannot provide any information about pole position NASCAR. However, NASCAR races are one of the most popular forms of motorsport in the United States and are characterized by high speeds and tight competition. Drivers compete on a variety of ovals and road courses throughout the season, with the ultimate goal of winning the championship title.
