What effects did the internal combustion engine have on transportation?

The Internal Combustion Engine was a extreme improvement of the best engine of its time, the steam engine. The internal combustion engine was smaller and far more powerful for its size. Since the discovery of SpindleTop, which produced massive amounts of oil, a source of fuel was freely available for the new engine. Since the extreme amount of oil was found, oil prices dropped, the internal combustion engine became more practical, and cheaper than a steam engine, which used Coal instead of oil, which back then was extremely cheap.

The thing about oil is that oil is also cleaner than coal, and is easier to transport. After Spindle Top Oil Barrels cost about 4 cents, a Barrel contains 31 gallons of oil, which is about 3/5 of the Gas Tank of a Dodge Ram (52 Gallons).
