I’m replying in this new thread so that the Mermaid on Pirates Thread can either get back on topic or just die out.
You had stated that there was no way that the car could become immobilized. The wheel coming off is just an example. I’m sure there are numerous other ways that it could happen. The point is that if the car is immobile, the people would have to be evaced from the vine. If that was the case, then before the safety railing, it would have been extremely dangerous.
