I don't think there's a solution/behavior that you'd want from a real-world lift that can pass all of the levels. I think some of the levels require you to encode an unfair/odd strategy that just happens to work well for the case they provide, and I think the randomisation makes runs occasionally impossible. You can try all of the solutions on the wiki, and they don't consistently succeed, even where they're claimed to solve all levels.
