Dogs and automobiles.
Why do dogs love vehicles? There aren't any vehicles in nature. Insects ride everything (
sometimes in multiple levels!), but mammals don't have any experience of riding.
I suppose we'll never know
why, but this wonderfully Dickensian picture answers
when: as soon as humans invented the first self-propelled machines, dogs were proudly riding shotgun.
