I don&#x27;t know with 100% certainty, but I am guessing rules for class action suits state that once an agreement is reached, the &#x27;class&#x27; bringing the suit (i.e., the drivers in this case) cannot sue again for the same reason. That is, because new drivers would be a part of the same &#x27;class&#x27; as the previous class action suit, they have technically agreed to the previous agreement, whether or not one individual driver agrees.
