How do I make a spring arm follow a velocity not a rotation

Have a look at this approach, it’s based on the advanced vehicle template:

  • we check if all wheels are in the air
  • if they are, we check how fast the car is spinning
  • if it’s spinning fast enough, we switch the spring arm’s rotation from Relative (default) to Absolute
  • in absolute, the rotation is not affected by the parent’s rotation
  • when springarm rotation is absolute, the rotation follows velocity
  • when springarm rotation is relative (car is on the ground), it follows the parent
  • and you get to set the angle

You will, most likely, need to check another state - when the car is flipped on the roof. The template tracks that variable already and it’s called LowFriction - it’s used to modify physical material properties but can also be used to control camera behaviour.
