Road transportation has significantly changed the world by enabling faster and more efficient transport of goods and people. It allowed for increased trading and economic growth by making it possible to send more goods faster. Early roads were muddy and unreliable, but innovations like the wheel and inventions like macadamised roads made transportation easier and more dependable. Over time, roads and vehicles improved, which supported populations by facilitating trade, economic opportunities, and learning about different parts of the world. However, road transportation also introduced disadvantages like pollution, deforestation, and accidents that harm humans and the environment.
