Spazio di frenata

It is the distance travelled from the start of braking until the vehicle comes to a complete stop. It depends on the speed: the higher the speed, the greater the distance. Specifically, the pattern is as follows: if the speed doubles, the distance increases fourfold if the speed triples, the distance increases ninefold if the speed quadruples, the distance increases sixteenfold and so on (i.e., if the speed increases by n times, the distance increases by n squared times) In addition to speed, the braking distance depends on: the grip between the tyre and the road surface; it increases if grip is low (e.g., in the presence of snow, mud, oil, or a wet road), if the wheels lock, or if worn tyres are used the gradient of the road; specifically, it increases downhill and decreases uphill It is not true that it depends on the driver's reflexes (these only influence the reaction time).
