Games like rigs of rods

Rigs of Rods (RoR) is a free and open source vehicle-simulation game which uses soft-body physics to simulate the motion destruction and deformation of vehicles. The game uses a soft-body physics engine to simulate a network of interconnected nodes (forming the chassis and the wheels) and gives the ability to simulate deformable objects. With this engine, vehicles and their loads flex and deform as stresses are applied. Crashing into walls or terrain can permanently deform a vehicle until it is reset; however, not all vehicles in the game have flexible bodies.

Rigs of Rods was initially created as an off-road truck simulator, but has developed into a versatile physics sandbox game.
