Its petition discovered a sympathetic viewers at NHTSA, which says within the NPRM that the company “acknowledges the potential for unexpected challenges and re-evalaution prices for heavy-duty automobile producers.”
“The proposed adjustments in compliance dates for heavy-duty autos wouldn’t end in further prices; any further prices related to compliance would merely
