Unfortunately I don’t have good knowledge on doing things in C++ 
Somehow I still can’t believe I can’t achieve the same thing in BP.
I’m trying to understand your function here.
(Since obviously mine didn’t work lOl)
Calls StopMovementImmediately on the movement component
In BP: I did found the function of Vehicle Movement > StopMovementImmediately.
Then calls Mesh->SetAllPhysicsPosition(GetActorLocation());
In BP: I found the function for the Mesh to Set new Location.
Finally calls Mesh->SetAllPhysicsRotation(GetActorRotation());
In BP: I found the function for the Mesh to Set new Rotation.
But I don’t exactly understand in what causes the vehicle to teleport in your next description.
Greatly appreciate the help.
Shamelessly requesting more info XD
