A. All cars must have a roll cage, which is integral with the frame anddoes not encroach upon an imaginary cylinder, 20 inches in diameter, extending through the top cockpit opening directly above the seat. The roll cage should extend four (4) inches above the driver’s helmet when seated in the driving position.
How many cars ran Gas City last night that couldn't pass this rule if checked?
"does not encroach upon an imaginary cylinder, 20 inches in diameter, extending through the top cockpit opening directly above the seat"

I looked at the pictures I shot at Bloomington's USAC race, and I have pictures of 7 cars that ran the Bloomington show, that could not pass this rule if enforced to the letter.

I don't get it.
