Book excerpt: Automobiles, trucks and SUVs make their way through Manhattan traffic on a daily basis, clogging the thoroughfares with a constant barrage of noise and pollution. Here Michael Spano concentrates on the person behind the wheel, honing in on facial expressions and upper-body positions trapped within, yet protected by, the rigid structure of the automobile. The drivers appear unaware of the busy metropolis, revealing a segment of American car culture grounded in the urban locale.
