I am on a passenger seat something like 3 times a week, in france, for the same 15 min rides (about 5 different rides in a southern city), and each time there is at least one car who emits a very foul smoke, so foul we immediately roll windows. Most of the time those cars aren&#x27;t even so old.<p>I highly suspect french automakers to cheat too.<p>There needs to be many more random exhaust controls, or at least much tighter annual or biannual checks. I can&#x27;t even comprehend why it&#x27;s not the case already.<p>It&#x27;s not even a climate change problem, it&#x27;s a health problem. I caught a cold already 2 times this year, which was followed by a chronic cough that lasted 3 week after the cold went away.
