"I'm panicky about it, and the whole idea of moving to a place that has a big car culture has me apoplectic," Gunn toldNew York Magazine in a Thursday report. "I'm not a good highway person. I'm much better at back roads."
Production will take place in Los Angeles for five weeks, according to New York Magazine, which had Gunn wondering where he'll live.
"I may have a little lean-to inside the set, wherever it is, so I don't have to worry about travel," he told New York Magazine.
Gunn also addressed recent indications by Klum that such Project Runway catchphrases as "auf Wiedersehen" and "Make it work" might be shown the door after the move to a new network.
"No," Gunn told New York Magazine. "I couldn't possibly. 'Make it work' comes with me. I've been saying it for decades."
Project Runway's fifth season -- most likely the last to air on Bravo -- will premiere Wednesday, July 16 at 9PM ET/PT. After production on that is complete Gunn will begin work on Bravo's Tim Gunn's Guide to Style reality series and Project Runway's sixth season, which Lifetime has slated to debut in November.
"I have no vacation plans," Gunn told New York Magazine, adding he doesn't get a day off until September 22. "I'm traveling to the Project Runway set."
Despite his hectic schedule and concerns about having to make the cross-country flight, Gunn's spirits aren't dampened.
