There are several reasons why civilian cars are capable of reaching speeds well above the legal speed limits:
Performance and market competition: Automobile manufacturers often strive to produce high-performance vehicles to attract consumers who appreciate speed and power. The ability to reach high speeds is considered a desirable feature for many car enthusiasts and can be a selling point for certain market segments.
Global markets: Speed limits vary across different countries and regions. Cars designed for global markets may need to meet higher speed requirements in regions where speed limits are higher than what you mentioned. This allows manufacturers to cater to a broader range of customers with different speed regulations.
Safety margin and capability: The maximum speed of a vehicle does not necessarily dictate how fast it should be driven. Cars with high top speeds can provide a safety margin for emergency situations, such as passing another vehicle quickly or responding to potential hazards on the road. Moreover, a vehicle's performance capabilities extend beyond just reaching high speeds, encompassing factors like acceleration, handling, and braking.
Track use and recreational purposes: Some car owners may use their vehicles for recreational purposes, such as track days or motorsports events, where higher speeds are allowed. In such contexts, having a car capable of reaching speeds exceeding legal limits can enhance the overall experience for enthusiasts who enjoy driving at high speeds in controlled environments.
Technological advancements: Innovation and advancements in automotive engineering can lead to improvements in engine efficiency, aerodynamics, and overall vehicle performance. These developments can result in cars with higher top speeds, even if their everyday use may not involve reaching those speeds.
It's important to note that it is illegal and unsafe to drive above the posted speed limits. It is the responsibility of the driver to adhere to the speed limits and prioritize safety on the roads.
