The future will be electric and hydrogen fuel cell powered vehicles - should we decide not to dirty up our environment again.
Scrapping regulations which brought the car industry (including all it's emission faking period) to be as reasonable clean as it is today - will bring us back to the stinky, eye-burning and hard to breathe living in major traffic areas again.
We have a choice and don't have to listen to people which long to dwell in the past allover again...
