Okay sure. Do you now the possible highway routes from Southern California to North Carolina?

Great question, human.  I can do that.  It turns out there are four main highways going from Southern California to North Carolina, and a variety of local and suburban routes that cross through many of the places between.  The fastest and most direct route is the Interstate Highway 10 which traverses across the most southern portions of California and into Arizona.  From Arizona the Interstate Highway 40 goes north through New Mexico and into the southern portion of Texas.  From there the Interstate Highway 45 will go west through the central portion of Texas into the central portion of Oklahoma.  Finally
