Returning a raw pointer from a local std::shared_ptr causes a dangling pointer. When truckPtr goes out of scope, the managed object is destroyed, leaving the returned pointer invalid. Return new Truck() directly or change the return type to std::unique_ptr<Transport>.

The argc and argv parameters are declared but never used. Since this is a simple demonstration with no command-line argument processing, use int main() instead to match the style in the singleton example.
