A very thorough explanation of how to drive on downhills.
This is one reason I love manual transmissions as you can drive down the hill with the throttle and not be touching the brakes unless necessary for the odd tighter corner.
Definitely worth sharing to friends and family to help to keep them safe as we all have seen too many people driving down the hill with the brake lights on the whole way down or almost the whole way down be at a small downhill or a long downhill.
Safe driving !
