If this is a realistic setting, how is Sonic able to straddle and stand upright on a speeding missile?
If Robotnik doesn't know who or what the blue blur is, why does he respond to his robot with "Him?" when it confirms they have Sonic on visual?
Why does Robotnik send unarmed, unescorted robots to search for Sonic when he's already decimated his buzz bombers? Especially when he's got smarter, deadlier robots he could deploy? And if they have Sonic on visual, why scan for him?
