I think it's a really weird situation where everybody has painted themselves into a corner: * the emission tests are extremely tight * the car industry is very competitive * loosening emission standards would be a politial issue As far as I know things started badly with emission tests not being representative and car manufacturers doing cheap fixes to pass them. Now would be a good time to fix this mess.
