Not too sure what data or how it is being collected, but DIDI does not operate its ride share services in the U.S.
U.S. can just block DIDI from operating the ride share service in the U.S. rather than delisting.
I don't believe delisting is what the U.S. wants to do, too many deep pockets already invested in DIDI and the moves out of China and concessions by DIDI do not indicate that a delisting is at the top of the list.
