  • Optical illusion is most likely the reason instead of engine brake if your vehicle slows down significantly in certain areas and doesn’t on other downhills with “similar” angle.

    There is this slope near a waterfall around where I live. If you put your car in neutral gear at the bottom of the slope, it rolls “up” the hill. We named it magnetic hill back in high school, but I later found out that it is just an optical illusion that happens everywhere around the world. Basically some uphills look like downhills and vice versa. Google “gravity hill”.
