The answer is:
Driving a vehicle at high speeds in a straight line for an extended period can lead to driver fatigue, distraction, and even drowsiness, all of which are unsafe. Roads that transition from straight to curved help maintain driver concentration better.
Additionally, road builders consider that while a powerful vehicle can climb a steep road easily, heavily loaded trucks or passenger vehicles cannot. A straight, steep incline is particularly dangerous when descending, as it makes speed control difficult and impairs the driver’s visibility.
When designing curves, builders aim to increase the curve radius and reduce centrifugal force, making it easier for vehicles to navigate the turn even at high speeds.
In summary, although winding roads may take longer to travel, they ensure greater safety. Driving on a steep, straight road is like playing a dangerous game that most people wouldn’t want to try.
