Why this chapter
You do not need to be a mechanic, but you must understand what makes the car go, stop and steer – and where the limits are. Brakes, ABS and stability control, tyres and grip, lights and visibility, and what is different about an electric car: this chapter gives you what you need to answer correctly and drive safely.
