We investigated whether humans could show a curving surface by constructing a dimension-reduced flattened 2D map or a full 3D map. Overall, the path distance estimation was fair, but we discovered a significant underestimation bias for the course distance on the curve, indicating an influence of future 3D shortcuts even though participants were only driving on the road. Participants were introduced more to the global 3D system of the environment by looking and flying, and Euclidean distance estimates was higher when participants were exposed more to the world 3D system of the climate.
