“To be honest, I didn't get to a point where I asked Christian,” added Ricciardo, referring to the Red Bull team principal Christian Horner. “If I did it, I would want to do it properly. I would hate to go there and get my ass kicked basically. Then it looks bad on F1 as well. The cars would be so different, I would want to make sure that I tested and got comfortable.
“In the calendar there were some races that I could do which didn't clash, but the question was when could I do the testing. This is even before asking Red Bull, but just in my mind I was like, ‘When could I test? When could I get to America?’”
Ricciardo, who has finished as high up as third in the Formula One World Championship when he took three wins during the 2014 season, admits that he still has some goals that he’d like to achieve in F1 before considering a career switch.
“The world title is the real one,” added Ricciardo. “It will wait a little bit, but sure, one day, I think I will definitely take up his (Dale Earnhardt Jr’s) offer.”
