Inertia classes, vehicle emissions tests, and the dead hand of the past

Test procedures are a key feature of any system of regulating vehicle emissions. Vehicle emissions testing* involves running a vehicle on a chassis dynamometer, which (among other things) simulates...The current system of using inertia classes for vehicle emissions testing is an anachronism, kept in place by force of habit rather than force of logic. And it has the bad effect of allowing...
