I think this is just not a concern for the general population. There are solutions available if we wanted to address this issue.

There could be a restriction on the vehicle. Some European cities have zones with restricted access to vehicles based on their CO2 emissions. There are stickers that you have to put on your windshield to drive into those areas.

We could have some "noise emission" regulations that ban some vehicles from driving at certain times, like before 9am or after 7pm.

It would be similar to the CO2 emission regulations, there's no need to measure the emissions because you have a sticker that already say what your emission levels are.
