It’s dreary and raining in “the CBD” of Auckland, 11 a.m. on Tuesday in the thick of New Zealand winter. A video conference connects with Scott Dixon, who has called from his home in Indiana, in the stickiness of a Midwest summer, where it is 6 p.m. on Monday. Dixon grew up in Auckland until his racing dreams took him to Australia at age 16. And then two years later, accidentally, all the way to America. It is in the United States where Dixon has a two-plus decade run as the greatest IndyCar driver of his generation.
