Fan reaction to the milk snub was highly negative, and he was booed a week later at Milwaukee, a center of the American dairy industry. In the years that followed, many fans continued to hold the action against him. In interviews since, Fittipaldi explained his action, and apologised for the wave of negativity that followed. Fittipaldi returned to Indianapolis to drive the Chevrolet Corvette Pace Car for the 2008 Indianapolis 500. Despite the passage of 15 years, he was again booed and heckled by some fans during the parade laps.
