The test include some acceleration. The duty cycle of full throttle is so minute that it's not a significant issue.
Also, a 20 year old car would be 1995 model year, which is still reasonably good.
Most people are basically innumerate and simply cannot comprehend the many orders of magnitude improvements made over the decades.
Look elsewhere. Modern cars are emitting exhaust that can be cleaner than ambient. Fact.
The issues facing us today are not caused by the 'skeptics' and 'deniers'. The vast ignorance of the well meaning population is the primary impediment to progress. People don't know enough to know what needs to be addressed first vice later. Useless.
