Owning a car brings about convenience that even public transportation, no matter how fast or efficient, cannot match, especially when you have kids etc. But honestly if its just you alone, or even with a spouse/partner, you can simply rely on public transportation.
And got jokers say time = money, if you drive spend 20 mins vs public transportation spend 45 mins, you think you can really save on that 25 mins to come churn out a significant amount of money? Plus nowadays got private hire which is even more convenient and cheaper as well.
