Actually, since you mention large pickup trucks: I've been surprised, pleasantly, at the number of these individuals who accept the going rate of speed and are some of the more courteous drivers on the road. Maybe they are secure enough in their masculinity that they don't have the need to bully others in order to prove their virility. Like the big schoolyard kid who turns out to be a gentle giant.

It always cheers me up when I see stuff like this, which contradicts the stereotypes we usually hold onto.
