Every hill, cliff and pit here is a polyline with real surface normals. A wall stops the car because the wall pushes back, not because a height limit was crossed. A slope steeper than atan(μ) = 42° cannot be climbed: the driven axle can only ever push with μ × the load on that axle. The pit at the far side has 58° walls. Fall in and the only way out is the rocket.
