Cars Used to Have Grounding Straps Hanging from the Back Dragging Over the Road: What Was the Use and Why Are They No More Used?
The Use of Grounding Straps
Grounding straps were used in older cars to prevent the buildup of static electricity. Static electricity can be generated by the friction between the car's tires and the road surface. If not properly discharged, this static electricity can damage the car's electrical system or even cause a fire. The grounding strap provided a path for the static electricity to discharge into the ground, preventing it from building up on the car's body.
Why Are Grounding Straps No More Used?
Grounding straps have become obsolete in modern cars for several reasons:
- Metal Bumpers: Older cars had metal bumpers that were directly connected to the car's chassis, providing a good path for the static electricity to discharge. Modern cars, however, have plastic bumpers that do not conduct electricity.
- Anti-Static Tires: Modern tires are designed to be anti-static, meaning that they do not generate as much static electricity as older tires.
- Improved Electrical Systems: The electrical systems in modern cars are more resistant to damage from static electricity, making grounding straps less necessary.
