Johnson set to leave race for birth of kid
The golf cart will be ready to whisk Jimmie Johnson to the helicopter, which will be waiting to rush him to the plane.
The four-time defending Sprint Cup champion has all the details covered in case his wife goes into labor while he's at Sonoma this weekend.
He and wife Chandra are expecting their first child next month. The baby is due during the break between the July 10 race in Chicago and July 25 in Indianapolis. But Johnson is prepared should he become a father early.
Part-time Cup driver Aric Almirola is set to serve as an emergency fill-in if need be.
Johnson just hopes he can drive at least the first lap of the upcoming races, because that would mean he'd receive any points the car earns.
