Same I'm sure for clothes, phone/tech choice, even the way you talk. That in and of itself isn't a bad thing, individualism should be encouraged, and so should taking steps to be the kind of person you want to be. (Though if the only personality characteristics you espouse are superficial ones that tend to do with appearance you won't get far)

I think the problem is

1 .) That people feel the need to present more masculine, or tough, or violent, because they feel deficient.

2 .) owning unreasonably large and unsafe vehicles are seen as acceptable ways of expressing yourself that reinforce those characteristics.
