Narrative:

I was working ground 2 which is the north ground position at lax. A super was exiting 24L and contacted me for instructions. I told him to taxi straight ahead on aa and hold short of charlie. I specifically told him to do that because of prior events and occasions in which foreign and non foreign carriers stop after exiting 24L when told to taxi via the 'bridge route'. Instead of me telling aircraft X to taxi via the bridge route; I specifically told him to taxi via aa and hold short of charlie. He read it back and I told him to contact ground 120.35. After looking up again; I noticed that he not only stopped; but he appeared as if he was attempting to turn left onto echo which was contrary to my instructions. Meanwhile; local 2 had an aircraft on or near the runway from what I can recall and could have cleared him for takeoff using anticipated separation as they watched aircraft X continue to move. This has been an ongoing problem with pilot's expectation bias of turning left onto echo when told to do something else. After I used a louder voice to reclear aircraft X on aa; he started to move and complied. I would recommend a notice going out to all carriers with a special attention given to the carriers which fly the super to lax about pilot expectation bias and the safety concerns regarding that. Pilots should comply with instructions given unless an emergency exists; or at the very least they should ask questions and ask for assistance if and when applicable. Because pilots think it is quicker to turn on echo to get to their gate; they presume that the ground controller will give that instruction. When they don't; the pilots slow down and often times stop to question the clearance.
