Your comment is greyed out as if it was downvoted a bit, which seems quite bizarre to me.

I think we’re pretty clearly talking about a small number of contrary data points, here? I’m not trying to prove a general trend at least, just point out that we should at least double check the assumption that expensive implies shared.

If someone is really invested in that idea I’d love to see an argument for it, rather than silent downvotes.

I haven't downvoted but your first post point out that it's negatively correlated. It seems to non correlated. An example is a car shared by family.

I know plenty of middle class parents who bought their teenagers an old beater because they didn’t want them driving the car they needed to get to work or their expensive car.

Wrecking your first car is almost a teenage rite of package.

Again we are talking about people who are willing to spend $3500 on a headset. Not exactly the demographic of people who are “sharing a family car” and that don’t statistically have separate cars for the parents and don’t either buy their kids a car or subsidize them in some way to help them buy their own.

I know I never let either one of my sons drive my car alone and I bought myself a new car and handed my older one down to my older son and bought my younger son a car before he had a license.
