First of all, my solution is better
Second of all, I proved it to be optimal, strictly
Third of all, I gave a family of solutions and
Last of all, after reading KangMM's solution, I identified that her optimal conditions are over strict, in that it is not necessary when the car is moving ahead, it has to carry 3 people as much as possible.
