How does this relate . . . car speeding down the road at 70 MPH . . . sharp curve . . . now what??? How do that relate?
IMO It relates in that hand speed and acc #3 rhythm must be coordinated SO THAT THE CAR CAN GO STRAIGHT ON!- at the fastest possible speed.
The car is not on the end of your arm.This is not a good analogy as the cars grip relies on friction -and the golf swing does not.(at least at the flail end!)
