Famous quotes containing the word car:
“The car has become the carapace, the protective and aggressive shell, of urban and suburban man.”
—Marshall McLuhan (1911–1980)
“Did ye not hear it?—No; ‘twas but the wind,
Or the car rattling o’er the stony street;
On with the dance! let joy be unconfined;
No sleep till morn, when Youth and Pleasure meet
To chase the glowing Hours with flying feet.”
—George Gordon Noel Byron (1788–1824)
