Level 4 means full autonomy over all normal driving conditions. Waymo does not handle complex construction sites like a normal human driver would, a fact verifiable by many thousands of people. It does not have level 4 autonomy.
Looks like the article got backlash too because the editor inserted an editor's note in quite large font right in the middle of the article clarifying it.

Aren't you describing Level 5?
From what I see online, Level 4 means
"The car can operate without human input or oversight but only under select conditions defined by factors such as road type or geographic area"
Waymo has been operating geo-fenced self-driving cars without drivers present. It may not handle complex situations, but that isn't expected out of L4.
Level 4 means full autonomy within certain predefined conditions. In Cruise's case, this might be, "Only in certain parts of San Francisco at night." This qualifies for Level 4.
