The problem with this game is that it's also used by other NPCs and works even when the NPC isn't in a vehicle, but it's also used for the quest "Into the Pit."
Here, the player has an action bar with exactly this spell, and it's supposed to trigger the knockback: https://www.youtube.com/watch?v=BIKdu9PS4p0

It probably needs a custom attribute or spell script to allow the knockback to effect vehicles. I'm on my phone so can't check the source code.
If you wanted to debug it, check spelleffects.cpp. This defines the Impl for each effect type. If you check knockback, you should be able to follow it through and see where it validates targets

I've already tried it with a spell script in different variations, and I've also patched the dbc directly and changed the spell without success.

Is it a world boss or dungeon boss? I doubt it
Does the vehicle have unit state root? Maybe, check npc info command output

No, it's not a dungeon or world boss, and the NPC isn't rooted either, because he follows me and attacks me. I've already checked all of that.
