The frustrating symptom is pressing your usual vehicle exit input and accidentally activating the Stuntjock action. The correct fix is input separation, not changing the vehicle or resetting your save.
Separate the two controls.
Keep the everyday exit action easy to access, and move the optional perk action.
Stuntjock — safer input setup
Do this in order.
A direct walkthrough without unnecessary detours.
Open the PC Controls / Key Bindings menu.
Look for the action associated with Stuntjock and jumping out of vehicles.
Pick a different binding.
Avoid assigning the same key used for a normal vehicle exit.
Check for conflicts.
If the game flags an existing assignment, change the binding rather than overlapping inputs.
Apply and retest in-game.
Check that your normal exit now works as expected. Avoid trying to reproduce a cinematic stunt in the real world.
Why this became easier after 2.3.
Before Update 2.3, players complained about overlap with the perk’s exit-jump action. The official patch note confirms that the key for this action can now be rebound on PC. Combining abilities such as Sandevistan is a separate in-game build choice; it is not needed for this control fix.
Quick questions.
Was this a 2.3 feature?
Yes. Official patch notes added PC key rebinding for the Stuntjock vehicle-exit jump.
Do I have to remove Stuntjock to fix the conflict?
No. Rebinding is the relevant option on a supported version.
Does this change normal exit controls on console?
The documented 2.3 feature is in PC-specific notes. Console control options can differ.
