Reasons not to coast
Although coasting used to be a common practice to save fuel, rolling downhill or approaching a junction with the car out of gear is inadvisable because you don’t have full control. You lose the ability to suddenly accelerate out of tricky situations and you lose engine braking which risks brake fade on downhill stretches – overheated brakes require harder pedal pressure to stop the car. In today’s modern cars, electronic engine management means that when you take your foot off the accelerator the fuel supply to the injectors is cut anyway, so there’s nothing to be gained by coasting.
