this picture as you can see was taken in a busy american city this picture was taken at exactly the same time and at the same spot question how was it done a modern motion picture camera photograph the traffic in action while but the care camera the great great granddaddy of all cameras was used to photograph the buildings all the action of this camera is so slow that there isn't time for moving objects to register on the film on the other hand the buildings being stationary gradually formed a sharp clear image and why use but the gare camera to show that any picture of america without automobiles is hopelessly out of date so they the automobile is part of any american scene every man woman and child in america could go riding at the same time and if we wanted to we could all ride in the front seat because there was a car or a truck for every three persons almost fifty million motor vehicles how many are fifty million cars bumper to bumper they would stretch around the earth that the equator seven times the distance we drive our cars and trucks every day would take us on five daily round trips to the sun but the real importance of the motor car is in the way it has opened up new  our way of living and that brings up a very interesting fact about one out of every seven american workers let's see what it is about that one worker out of seven one two this man is a two tester he listens to automobile horns in a factory to be sure they are tuned to the proper musical tone if anybody should ever ask you what the proper musical tone is it's combined with g let's try again apartments there but would you tell us what business you're in for a thirdly i'm a farmer and what do you grow on your farm well you might say i grow automobiles because i own part of the four million acres of farmland used to grow raw materials for pain lacquers and insulation used in motor cars and you say it seems that your a minor but what do you min get answers like that in any crowd anywhere from any one of over nine million men and women who make their living directly because of automobile transportation that's what we mean by one out of seven let's see how many it takes to make over nine million people will begin with the city of los angeles which has become our fourth largest city suppose every family in los angeles should decide for some reason to move elsewhere the supposin to each house left vacant there should move of the family of a worker in the automobile industry the one man out of seven actually los angeles isn't nearly big enough to hold them all nor for that matter is the whole state of california you see there be the steel workers the men who make steel for the automobile and their families be the families of glass workers who make automobile glass we have to find homes for the families of all the workers will build tires and batteries and cars and we have to make room for the eight hundred thousand families a man in the big motor car and truck assembly plants as it would be moving day for one out of every seven families in the united states and we have to include the moving van driver and his family to because you see he is one of more than five million drivers who drive for a living buses and taxis and while you're about it did you ever stop to think of how many people it takes to maintain our roads and highways well quite a few because on the highway miles of america we could drive to the moon and back more than fourteen times well does that account for one out of every seven workers in america not quite but it does when you add the man who sell motor cars and the man who service them moving the family is about one worker out of seven gradually replacing family per family we need all the houses in california oregon and washington i don't know utah and arizona montana wyoming and colorado and part of texas still find homes for the people who make their living directly because of the motorcar and this brings up an interesting question what would these people be doing if the motor car had remained a luxury for a few rather than a necessity for so many and what about all the people who depend indirectly on the motor car for the way they live looking at it this way we can fill up all the homes from north dakota to texas and from minnesota to arkansas all the way to the bank the boras the meter man the rural mail carrier and of course the more than two million salesmen on the road now it seems that we found out something else about the kinds of jobs that you might not even think of as being connected with the motor car the traffic policeman and the people who make and sell traffic lights and parking meters but what you think of railroad engineers you would if you knew that transporting raw materials and finished products to keep our american system of individual transportation by motor car rolling takes four million freight car loads per year one sixth of all retail business firms are connected with the automobile even including little jimmy's first business venture the motor car makes business for america and one out of every five of retail sales dollars in america changes hands being able to drive out into the country has made many of us want to live in the country and the motor car has made it possible for millions today suburban construction is more than three times the construction in the city and just as the motor car is a tool for working with more than half of us using it to go to and from our daily work so it is a tool for enjoyment it puts america at our doorstep for business or pleasure whether you're traveling on business or pleasure the chances are even that you'll travel by motor car more than half of us take your leave occasion most of us take them on the highway as a result the tourist and resort industry ranks among the three most important industries in sixteen states we have seen how the de guerre camera a camera from the past can take a picture of the past to show how our horizons have been expanded by the motor car and the greatness of america has been that we are never content to stop on the horizon we can see we know that there is another and another horizon beyond the motor car industry as it has recognized its responsibilities and our progress through yesterday to get where we are today is already at work on the design of tomorrow exploring developing testing to improve the cars we drive to make them safer more comfortable more enjoyable if we are realize in full the motor cars vast potential for good we must use it and care for it wisely the motor car has been the key to open new horizons not for the few but for all and all of us share in the responsibility of safeguarding the benefits it has brought if we plan for the future if we look ahead to clear all obstacles and roadblocks if we recognize the importance of this great individual freedom of movement
