Joshua Joyce has just had the Seed delivered to him and takes it to Bejing to complete his Transformium project. Cade Yeager calls him on his cell phone and convinces him that Megatron has infected his Galvatron project, and intends to use the Seed to cyberform a major city, using it to create enough Decepticons to wipe out humanity and take over the planet. Joyce actually listens to Yeager, and tells Harold Attinger that he wants to delay implementation of the Seed. Attinger orders his henchman James Savoy to kill Joyce and get the Seed at any cost. Megatron takes over the Galvatron shell and orders the other KSI prototypes to get the Seed. Joyce escapes Attinger and Megatron, with his associate Su Yueming driving him to Hong Kong China is a rather large country, with a land mass fairly close to that of the continental US (minus Alaska and Hawaii). And even though the major cities are chock-a-block full of cars, most distance traveling is done by rail or air. Google cant even create driving directions from Beijing to Hong Kong. The best it can do is show the air route or the twice-daily train route. Yet Yueming manages to drive Joyce the 2,000 kilometers from Beijing to Hong Kong in record time.
