Human psyches are hardwired to fly, it seems – whether the “flying” consists of speeding straight ahead in our cars on eight-lane freeways or soaring through the air in silver-winged jet planes at 500 miles per hour. In ancient times, we sped from place to place in horse-drawn carriages and chariots.
In neither age have we gotten it quite right, however. Transportation was, and still is, a mixed bag. Eric Morris, a doctoral student in the UCLA department of urban planning, writes in an Internet article that horse pollution was so bad in ancient Rome, Julius Caesar had to ban horse-drawn carts between dawn and dusk in an effort to curb ”noise, gridlock, accidents and other unpleasant byproducts of the urban equine.”
Such problems continued well into the 19th century, when both the human and horse populations soared, not just in Rome, but across Europe and then America.
