From 1966 (when there was essentially no emission controls) to 1986 (when almost all cars had fuel injection with closed-loop control and catalytic converters) the VAST majority of harmful exhaust emissions were eliminated. It became essentially impossible to commit suicide from exhaust because carbon monoxide levels were so low. Since then, it has been a constant march of annual new emissions standards from the EPA and CARB which served no purpose other than to reduce the already tiny emissions levels to even more microscopic levels, which consumed huge amounts of R&D budget to constantly develop. Can you imagine what it will be like when we have a STATIC emissions standard and all those R&D dollars can go to improve crash safety, fuel mileage and styling? AUTOMOTIVE RENAISSANCE!
