However, instead of simply mandating maximum emission levels on new vehicles, 'cats' were mandated which then negated the work Ford, D-B, and others had done on 'lean-burn' technology which, in fully developed form, would have made 'cats' unnecessary and saved the energy and emisions caused by the manufacture of cats and the increased fuel consumption cats cause. Again, the bloody politicians screwed up and actually increased pollution by their stupidity Nothing new there then!
Indeed, but mandating catalytic converters (a) ensured the stiochometric ratio of fuel/oxygen used by vehicle engines was effectively fixed thereby preventing significant increases in vehicles' mpg that would result from lean burn technology, and (b) that big bung in your exhaust system increases fuel consumption by an average of 10%. The spoils go to the oil companies and the government taxing the fuel.......
