A young man noticed an elderly lady following him around while shopping in a supermarket. She stopped when he stopped and kept staring at him. Eventually, at the checkout, she approached him and said, “I hope I haven’t made you feel ill at ease; it’s just that you look so much like my late son.”
The man replied, “That’s okay.”
She then made an unusual request: “I know it’s silly, but if you’d call out, ‘Goodbye, Mom’ as I leave the store, it would make me so happy.”
Obligingly, as she left, the man called out, “Goodbye Mom!” She waved and smiled back.
Feeling pleased for brightening her day, the man proceeded to pay for his groceries. The clerk said, “That comes to $121.85.”
Surprised, the man exclaimed, “How come so much! I only bought 5 items.”
The clerk replied, “Yeah, but your mother said you’d be paying for her things too.”
Why is that?
The Answer is:
If a vehicle drives in a straight line at high speed for a long time, it will cause the driver’s vision to become fatigued, attention to be distracted, and even lead to drowsiness, which is unsafe. Therefore, driving on a road that changes from straight to curved will stimulate the driver’s concentration better.
Not to mention, builders also consider that a powerful vehicle can easily climb a steep road, but a heavily loaded truck or a passenger vehicle cannot. Moreover, a road with a straight, steep incline is extremely dangerous when descending, as it is difficult to control speed. A steep incline can also affect the driver’s visibility, making it hard to see ahead.
When designing curves, builders try to increase the curve radius and reduce centrifugal force, allowing vehicles to handle the turn more easily even at high speeds.
In summary, while winding roads may take more time to travel, they ensure greater safety. Driving on a steep, straight road is akin to playing a dangerous game that most people wouldn’t want to try.
