NASA and Goodyear have developed an airless, superelastic “Superelastic Tire” made from Nitinol wire mesh

 NASA and Goodyear have developed an airless, superelastic “Superelastic Tire” made from Nitinol wire mesh. It recovers from 8–10% deformation on lunar and Martian terrain, preventing cracks. Lightweight and cold-resistant, its fatigue life and production costs are still under evaluation, and actual deployment is planned for next-generation rovers. By solving the cracking issues of aluminum wheels, it also eliminates flat tires. Tested on analogue courses in the U.S. and Europe, it’s being considered for Artemis lunar rovers and future Mars vehicles. However, long-term fatigue data under extreme thermal cycles and scalable manufacturing processes must be matured, so challenges remain.

In practice, the most workable approach is to measure a composite “civility score” built from multiple indicators.

  1) Model-based indicators (machine learning) Toxicity/Aggression: Use Jigsaw’s Perspective API to obtain probabilities for “TOXICITY,” “INSULT,” “PROFANITY,” “IDENTITY_ATTACK,” etc. Japanese is supported (see the official language table). Politeness: Stanford’s research established a framework for estimating “politeness” from markers like request forms, hedges, honorifics, etc. It’s English-centric, but the methodology can be adapted to Japanese. The R package politeness is also useful. 2) Lightweight rules for Japanese (highly interpretable) Honorific/hedge rate: Ratios of “です/ます,” “〜でしょうか,” “お手数ですが,” “お願いします,” and the like. Presence of slurs/derogatory terms: A custom NG-word list (including figurative or euphemistic forms). Imperatives/strong assertions: Frequency of “〜しろ,” “〜に決まってる,” heavy use of exclamation marks, ALL-KATAKANA bursts, etc. Consideration/evidence markers: Signs of dialogic and verifiable style such as “根拠：,” “出典：,” “もし〜なら.” 3) ...
