You cannot compare a Laboratory test to gathering data in the Field. In the USA we have the FTP which is used to determine compliance. The FTP is a scientific test were all the parameters are controlled for repeatability and accuracy. Temperature, humidity, driving cycle, specific fuel are all closely monitored for accuracy. This laboratory test allows for repeatability to achieve accurate results.
Driving the same car in "the real world" is not a valid test. There are too many uncontrolled variables in the real world to state whether the car meets or doesn't meet the applicable standard when the standard is determined by a controlled laboratory test.
Now, do the car manufacturers design the pollution equipment to pass the FTP? Of course they do, because that's the standard they need to meet.
