What it appears to be actually calculating is that 1/9 of items had majority consensus that they were against the rule. It doesn't appear to take your actual selection into consideration, only the amount of questions answered
You are right, the "all violate" and "all do violate" options both give 2/7 = 29% for the first 7, which is the majority opinion (car and ambulance violate, the others do not).
