text: Source 2 talks about how Paris has banned driving due to smog.  Congestion went down 60 percent in the capital of France.  Delivery companies in Paris complained of lost revenue, while exceptions were made for plug-in cars, hybrids, and cars carrying three or more passengers.  The advantages of limiting car usage here is the you'd never have to worry about there being smog outside or snow etc.  Limiting car usage, you wouldn't have to worry about the weather being so terrible that you can't drive in smog or heavy rain and have a car accident.
