The most common term for sharing a taxi with other passengers is a "shared taxi" or "jitney." In modern tech-speak, especially when using apps like Uber or Lyft, it is often referred to as "ride-pooling" or simply "pooling." In various cultures, specific regional words exist for this practice: in some parts of Africa and the Caribbean, they are called "bush taxis" or "maxi taxis," while in the Philippines, the famous "jeepneys" serve a similar purpose. In a more casual or historical context, the term "carpooling" is sometimes used, although that strictly refers to sharing a private vehicle rather than a commercial one. If you are specifically looking for the "ride-share" jargon, you might also hear the term "split fare" when multiple friends share one cab and divide the cost, though "shared taxi" remains the most accurate descriptor for a cab that picks up multiple unrelated passengers.
