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.
Why do some people place coins on gravestones?
Coping with the loss of a loved one is a challenging journey, even when they rest in a visitable site. Many individuals express their deep connection by leaving intricate offerings like flower arrangements, and in certain cultures, even snacks. However, the tradition of placing coins on gravestones holds a distinctive significance, primarily associated with military personnel, carrying a profound meaning for veterans and their families.
The origins of the practice are somewhat unclear, with claims suggesting a historical connection to the Roman Empire, though lacking concrete documentation, according to Snopes. Regardless of its historical roots, one undeniable truth remains, those who serve in the armed forces, along with their loved ones, endure sacrifices that often surpass common understanding.
The custom of leaving coins on gravestones can be traced back to the Vietnam War era, where it served as a practical means of communication amidst the divisive political climate surrounding the war. Leaving a coin became a subtle yet meaningful gesture, avoiding potential contentious discussions with the soldier’s family about the politics of the war. This revelation is shared on the American Legion Website.
Beyond its practical origins, the tradition of leaving coins on gravestones has evolved into a symbolic act of showing respect and honoring fallen comrades. Each coin type carries a distinct meaning in this poignant practice. A penny symbolizes a simple visit, a nickel holds sentimental value as it signifies shared experiences in boot camp, a dime represents serving together, even briefly, before a transfer, and a quarter, perhaps the most significant, indicates that the individual was present during the time of death, offering solace to the grieving family.
This tradition of military personnel leaving coins is not the sole connection between the military and monetary symbols. Challenge coins, a beloved military tradition, have deep roots dating back to World War I, symbolizing unity among those who have served. While challenge coins hold sentimental value and represent unity, they lack any monetary worth.
Coins, as symbols, extend beyond military traditions, playing roles in various cultural practices. Coins are often seen as symbols of good luck, goodwill towards newlyweds, and objects for making wishes. Throughout history, there have been instances of individuals being buried with their wealth, although not necessarily in the form of coins. Abraham Lincoln, for instance, was reported to be buried with two-half dollars over his eyes.
While the specific symbolism of currency may remain unclear in the tradition of placing coins on gravestones, the practice signifies a bond that transcends superficial understanding. It serves as a powerful and enduring tribute, acknowledging the sacrifices made by those in the service and their families, ensuring their dedication is never overlooked or forgotten.
