Until a day comes when all cars can emit clean gas, what about having aromatic car exhaust filters that make emissions smell like perfume, plants or flowers and not like mechanic farts? Wouldn't that help make our cities friendlier to live even though the level of pollution would still be the same? Even if clean emissions become reality one day, shouldn't we still require aroma to be emitted as a way to achieve large scale urban aromatherapy for all city dwellers cities?
