Only those long-term residents of Dehli who were extraordinarily sensitive to the vicissitudes of the city's traffic patterns could tell that rush hour had peaked and was now on the downward slope. The cacophony of horns, sirens, and screeches seemed undiminished to the tortured, untrained ear. The crush appeared unabated. There were gaudily painted trucks; buses with as many riders clinging precariously to the outside and on the roof as were inside; autos, ranging from hulking Mercedes to diminutive Marutis; throngs of black-and-yellow taxis; auto rickshaws; various motorcycles and scooters, many carrying entire families; and swarms of black, aged bicycles. Thousands of pedestrians wove in and out of the stop-and-go traffic, while hordes of dirty children dressed in rags thrust soiled hands into open windows in search of a few coins. Cows, dogs, and packs of wild monkeys wandered through the streets. Over all hung a smothering blanket of dust, smog, and general haze.
