So I've gotten on a kick of watching dashcam videos on YouTube. One thing I've noticed is that it seems really easy to knock the wheels off a newer vehicle.
I don't mean cracked rims, but completely separated knuckles, spindles control arms etc.

Are they intentially designed to do this nowadays? Or just a consequence of weight loss and efficiency?

Surprisingly, I even see this on trucks too.

I don't recall ever seeing stuff like that on older vehicles, at least ones that weren't completely clapped out or rolling tetanus mills.
