On a long downhill, the speed will increase due to gravity. Which method is correct for controlling speed?

ANSWER · B

Engine braking has three notable features: first, thanks to the differential, the braking torque is distributed evenly to the left and right wheels, reducing the chance of skidding or fishtailing; second, it greatly reduces the use of the foot brake, avoiding brake-pad overheating from prolonged use that reduces or eliminates braking force; third, it consistently keeps speed within a certain range, helping the driver slow down or stop in time and ensuring driving safety.
