I read that part as being a mashup of two disparate things similar to the rest of the piece. The CD seems to be announcing things more frequently, and there are places where the highways have no speed limits, both of which are more straws on the camel of anxiety.
The CDC is the Center for Disease Control, they have zero input on speed limits. Which are all state-dependant anyway. Very little of it makes any sense or is grounded in reality, I think it's a troll honestly.
