1.1Background Roads and Civilization  The wheel was invented in 5000 BC years.  This made necessary the construction of special hard surfaces of roads.  Ancient roads were built to suit the old mode of transportation (horses, donkeys and carts). Motor vehicles used these roads and in many cases they were not very suitable.  Roads improve communication and hence civilisation.  The prosperity of a nation is bound up with the state of its roads.

 History of Car  In 1769, the very first self-propelled road vehicle was a military tractor invented by French engineer and mechanic, Nicolas Joseph Cugnot.  Cugnot used a steam engine to power his vehicle,steam engine  Speed (2.5 mile/h)  The vehicle had to stop every ten to fifteen minutes to build up steam power.

 History of Car (continue) 1.1Background  In 1771, Cugnot drove one of his road vehicles into a stone wall, making Cugnot the first person to get into a motor vehicle accident.  This was the beginning of bad luck for the inventor.  After one of Cugnot's patrons died and the other was injured, the money for Cugnot's road vehicle experiments ended.  Between 1832 and 1839 Robert Anderson of Scotland invented the first electric car. Electric cars used rechargeable batteries that powered a small electric motor.  The vehicles were heavy, slow, expensive, and needed to stop for recharging

 History of Car (continue) Background  Around 1885s, the Early Gasoline-Powered Cars was invented which was better than the electric and steam engine cars
