Before trucks were motorized, they were drawn by animals. Any vehicle on wheels can be naturally connected with the male psyche. Boys and men are naturally drawn psychologically by mechanical motion, the faster the movement, the more intensely attentive is the male psyche. It's like natural predators that have prey-drive instinct. In primitive hunter-gatherer societies, men hunted: men pursued game for meat. Fellows like SPEED and power.
I am not sure if instincts concerning speed and power can be transferred to an innate response for trucks, though.
If there is, the shape of the truck could be an attraction for resembling an animal, but that should be a response for females as well.
Without evidence at an early age before adults begin surrounding their senses with specific images, it is impossible to dicern from an innate response and something that has been imprinted due to familial exposure.
I am willing to accept the possibility that there
could be gender differences in some innate responses (innate responses in humans is a convoluted subject among ethologists), but would add the caveat that humans are generalists and very adaptable, hence the great spectrum of behavioral differences we are capable of.
