When Eddie Rickenbacker started manufacturing cars in the 1920s, he hired Baker as chief test driver. Baker broke his own winter cross-country record with a 71 1/2-hour trip (driving time only). 

He also drove a Rickenbacker on a "three flag" journey from Vancouver, British Columbia, to Tijuana, Mexico, in 40 hours and 57 minutes.

Image from page 17 of Pan American Air Ways, Vol. 4, No. 3, June 1933. Caption reads: "Captain Eddie Rickenbacker, America's Ace of Aces in the world war, and "Cannonball" Baker, celebrated racing driver, about to embark at Dinner Key."
