1. Sequence((n, g(n)), n, 0, t_1) → list2
2. Segment((-1.9, 0), (-1.1, 0)) → road_0
3. Sequence(i - 0.4 < x < i + 0.4, i, 0, t_1) → photo_{road}
4. Sequence(x = i - 0.4, i, 0, t_1) → left_{road}
5. Sequence(x = i + 0.4, i, 0, t_1) → right_{road}
6. Sequence(x = i, i, 0, t_1) → mid_{road}
7. Sequence(Translate[car_p, Vector[(0, g(0)), (i - g_y(i), g(i))]], i, 0, t_1) → photo_r
8. Segment((-1.9, 200), (-1.1, 200)) → road_{200}
