Earlier quoted context omitted.
Respectfully, without judgement, your perspective may be wildly skewed because you’re American (going by your post history). I suspect the negative externalities in a society built around cars don’t register with you because to you it is the normal state of the world. As a Dutchman, I grew up in a built world that is based around the human scale and to me your parent’s claim comes across as astonishingly obvious.
The Netherlands has 513 cars per 1000 people compared to the US rate of 779. A significant difference, certainly, and it's plausible that there's a threshold effect where a society built around 50% more cars faces unique problems. But this doesn't at all seem consistent with the original idea that automobile technology itself is bad.
I'm also not sure that anyone was claiming automobile technology itself was bad, just that in many places at many times it has been used in suboptimal and harmful ways.
