The Automobile actually began about 4000 years ago when the first wheel was used for transportation in India. Several tailings recorded designs for wind driven vehicles. The first was Guidoda Vigevano in 1335. Vaturio designed a similar car which was also never built. Later Leonardo da vinci designed clockwork driven tricycle with tiller steering and a differential mechanism between the back wheels. For many years after the introduction of automobiles, there kinds of power sources were in common use; Steam engines, gasoline or petrol engines, and electrical motors. In 1900, over 2300 automobiles were registered in New York, Boston, Massachusetts, and Chicago of these 1170 were Steam Cars, 800 were electric Cars, and only 400 were gasoline Cars. The range of the automobile however, was very brief and at the most, it could only run at a stretch for fifteen minutes. In addition, these automobile were not fit for the roads as the steam engines made them very heavy and large, and required ample starting time. It had a top speed of a little more than 3.2 km/hand had to stop every 20 minutes to build up a fresh head of steam. A road thus made out of iron rails became the norm for the next hundred and twenty five years. The Automobiles got bigger and heavier and more powerful and as such they were eventually capable of pulling a train of many cars filled with freight and passengers.
