It’s hard to answer that in a way that applies to my real world experience, because driver behavior is a much bigger factor, and I don’t know how to separate that out. My experience (which is definitely biased toward what I notice) is that people drive big trucks more aggressively, and I don’t even think it’s intentional a lot of the time – people just don’t have a great sense of the space they take up.
And I guess some of that applies to men as well, but I don’t want to get too out on a limb with the metaphor.
