Why this chapter
Speed is not just a number on a sign – it is physics. This chapter explains reaction and braking distance, why stopping distance grows far faster than speed, what counts as enough distance to the car in front, and how road surface and load change the arithmetic. These are numbers you must know, not just have heard of.
