• A. Yes
• B. No

  The correct answer is B

   

  Shifting to neutral or coasting is actually very unsafe because you need your acccelerator to avoid unexpected hazards on the road. Disconnecting the engine from the drivetrain removes any engine braking. This means that your car will speed up without using your brakes, and relying solely on your brakes means you could get brake fade.
