How were cars invented?

Answer 1

The automobile is simply an extension of the horse-drawn cart or carriage. After improvements in mechanical linkages were developed for locomotives, the smaller engines were developed during the 1870s and 1880s. Some were steam-powered, but the ones that provided the dependable motive energy were the gasoline and diesel internal combustion engines. These were fitted to modified vehicles which became known as "horseless carriages." Eventually advancements in engines, transmissions, and fuels allowed cars and trucks to completely supplant the horse and buggy, and the armed forces replaced cavalry with tanks and trucks.
