youre being obtuse on purpose.. Its actually very funny. Youre literally disagreeing with what the Fn movie stated to the audience.. Youre laughable at best.
No the imperials had no clue to where Solo went, That's why they dumped their garbage while Solo and the crew hid against a tower on the star destroyer..
Fett took it upon himself to hide in the garbage shoot not the other bounty hunters who were also assigned with finding them. You clearly see the Star Destroyer go to hyperspace and Fett wait in the garbage while Solo revealed the Falcon (that had no working hyperdrive) obviously something Fett realized.
Thats more there than simply tracking. Fett literally outsmarted Solo at his own game. Vader and the Imperials as well as the other bounty hunters did nothing of the sort. BUT Fett did..
Vader even made it a point to specifically tell Fett, "no disintegration process." Did Vader say that to the all the other bounty hunters, the giant robot IG-88 or Bossk the giant lizard. NO he didn't. He specifically singled out Fett. Which just cements how much of a badass he is.
keep trying kid maybe youll actually watch the damn movie sometime.
