He turns the wheel left until his car is 7 degrees off of straight down his lane.
At the moment his car reaches 7 degrees, he turns the wheel back to straight to maintain the 7 degrees, until impact. What we are interested in is the force of the impact.
Compare to instead of only turning 7 degrees, and then straightening out, he decided to keep the wheel turned until contact.
This time he happened to be a little closer to the car when he turned, and coincidentally he was pointed 7 degrees at the point of impact.
Now remember, like the road bed / tire analogy, these cars are not under power (not accelerating) nor braking other than the slowing down due to the turning.
Both cars achieved the same change of direction, burning up the same amount of speed to get there, so they should have the same level of impact.
Same level of impact in bowling means the same amount of deflection, and therefore the same chance of carrying.
One was in the roll phase (maintaining 7 degrees), while the other was in the hook phase (still turning), which just happen to reach 7 degrees on it's way to more, until interrupted by the impact.
While I appreciate the analogy, this falls back under what I initially explained. The driver who is 'still turning' is splitting his tires traction (balls energy) between his forward direction, and the direction in which he is turning. Whereas the driver who is driving straight will impact 100% of its forward momentum into a single direction, and will more efficiently transfer it's energy into the object with which it collides (pins).
Also, if I recall correctly, a car accelerating to 60mph, will impact more force than a car cruising at 60mph, even if they both strike an object at the exact same speed. So, if we fall back to your statement a few posts ago, "maximum rev when it starts to roll, yes." or even your last post, "In terms of bowling, the balls speed is decreasing (road bed MPH) while the balls rev rate (Tire's MPH) is increasing." in both aspects you're describing an increase in the balls movement, in 1 form of another. That increase, will result in more energy (kinetic maybe?) applied to the object it collides with. Am I remembering my High School science correctly here?
It would seem logical that a ball that hasn't reached the 'increase' you've defined twice now, (still hooking) won't be as effective as a ball that DOES reach that increase (rolling) in regards to 'colliding' with the head pin. Right?
