I am thinking of creating a new type of Public Transport for people living in mountainous area. The idea is using a wooden sled that has break controls and it is used to transport people going down from the mountain by letting the gravity slide down the sled from the mountain and the break controls involves strongly holds the sled to the ground to stop the momentum. The passengers will have to wear helmet and holds air bag in case the sled slams hard on trees or huge rock
