If you are now in middle age, the chance is good that your grandparents were born before the automobile worked its enormous change on American life. In about four generations electrical power, the telephone, radio, TV, airplanes, computers, even space travel, have changed the way we live beyond recognition. But no invention, save perhaps the electric light bulb, has changed our day-to-day life quite so much as the automobile.That is the beginning of the end of an online history of the automobile in America. I found it while looking for something to back up a commenter's statement that the UAW drove Studebaker-Packard out of business.
