Question

road of hilly region has made long and innumerable bends why

Answer 1

Explanation:

The idea is that it's easier to exert less power over a longer period of time. Also, going down those steep slopes may cause more accidents than the winding mountain road. It would be too steep to rely on engine brakes, so you'd have to use your disk brakes more, which could result in more burnt-out brakes.
