You increase your speed from 50 km/h to 100 km/h. How is the braking distance changed according to the rule of thumb?

According to the rule of thumb in German traffic rules, the braking distance increases with the square of the speed. This means if you double your speed from 50 km/h to 100 km/h, the braking distance becomes four times longer, not just twice as long. For example, if the braking distance was 25 meters at 50 km/h, it will increase to 100 meters at 100 km/h. This is because braking distance depends on kinetic energy, which grows with the square of speed, making it crucial to adjust your speed to road conditions for safety.
