Weird.
I know a lot of carbrains, a and I have heard this precisely zero times in my life.
They do say it's expensive, though. And then the "I have children, I therefore couldn't survive without a car", while in reality children are in reality an obvious argument against using a car.
But yeah, the argument about expenses is funny.
The total cost of owning and using a car is around 300 โฌ per month. (And my parents say they are paying aboout 400 โฌ)
A public transportation ticket costs some 85 โฌ per.month.
It's amazing that people are willing to pay 300 โฌ to save 85 โฌ. And I woild say that's an argument I hear from at least 30 % of my city's adult population.
(But "dangerous" is an argument I have never heard against public transportation, in any case)
