What are the effects of driving at high speed in motor vehicles with combustion engines?

Driving at high speed in motor vehicles with combustion engines significantly impacts both the environment and efficiency. Firstly, increased fuel consumption occurs because engines work harder to maintain higher speeds, leading to less distance traveled per unit of fuel. This inefficiency results in higher costs for drivers and greater demand for fossil fuels.

Secondly, the emission of harmful substances rises as combustion engines emit pollutants more intensely at higher speeds. This includes an increase in harmful gases like carbon monoxide and nitrogen oxides, which contribute to air pollution and pose health risks.

In contrast, the claim that the noise level is reduced is incorrect. High-speed driving typically results in increased noise levels due to the engine working harder and wind resistance.

Understanding these effects is aligned with German traffic laws aimed at promoting environmental protection and road safety, highlighting the importance of responsible driving speeds.
