Just another example of rules being added for the sake of...something. If anything, this rule creates more problems than it solves - drivers hiding injuries for fear of being inconvenienced or having to sit out. Sweepstakes shouldn't be focused on adding more senseless rules when they can't even enforce or properly comprehend the current ones. As well as a general attitude of apathy from team's chairs, who just raise their hands to approve a rule change, because "why not?".
