On this planet I have humanoid creatures of a similar size to humans, however, they are physically stronger and faster. They also rate physical prowess very highly and as such are likely to be active rather than spending inordinate amounts of time and money on labour saving devices like we do as a species. So here are some questions that I would like your input on: - Travel Cars are unlikely to be necessary as travel by foot to a specific locale wouldn't be a major issue; however, a fast means of travel between hubs would be necessary. It would not need to stop at stations since it would be possible to board at relatively low speeds. It would not need to be a safe cocoon for its passengers since these aliens would find human levels of trauma quite survivable or avoidable. What would this be? Buildings Architecture is unlikely to segregate internal and external areas given that these creatures would probably be able to employ more of a parkour method of traversing the built environment. How would this effect design? Traditional walls would be an inadequate barrier to entry, what would be used in their place? How would buildings be secured? Stairs are likely to be an uneconomic method of vertical travel. What would be used in their place? I have come up with some ideas, but any suggestions or thoughts you want to offer would be appreciated.
