Large cities have to many people and machines in them.
Do people believe that they should still be able to burn hydrocarbons in the middle of a congested city in an older car because it is a classic??????????
Yes. The numbers of classic cars are tiny and the exhaust from modern cars is often cleaner than the air going into the engine. The main culprit these days is trucks ( but we need them) and busses. I wonder if Paris will cut back all the old smelly diesel busses
