Why is coasting so bad?
Tell me why?
Coasting is when the car is moving but it’s not being driven by the engine – either when the clutch pedal is held down or the gear lever is in neutral. Drivers occasionally coast along the road in when they are not in gear, so in neutral, when they are decelerating, or when going downhill. This saves fuel, and money, however, coasting may not necessarily be safe.
When a car is coasting it is slowing down due to mechanical and aerodynamic grip, and during cornering the mechanical component of this is higher due to the slip angles in the tyres. In essence, it is likely to cause an accident or a skid.
The Highway code states:
This term describes a vehicle travelling in neutral or with the clutch pressed down. Do not coast, whatever the driving conditions. It reduces driver control because:
- engine braking is eliminated
- vehicle speed downhill will increase quickly
- increased use of the footbrake can reduce its effectiveness
- steering response will be affected particularly on bends and corners
- it may be more difficult to select the appropriate gear when needed
People suggest that it is cheaper to repair brake pads or clutch, however this will cost you on your driving test, and more seriously this could leave you in an accident.
So remember: Avoid coasting
If your car is coasting you don't have as much control, and worse doing this while you’re travelling downhill will mean you’ll quickly pick up speed, and you’ll then need to brake harder than should have been necessary.
