I&#x27;d love to see some kind of universal &quot;Hailing&quot; API. Something that would allow a single app to coordinate rides wherever you go.<p>I travel as well, and really wish I didn&#x27;t need to have an entire folder of transportation apps on my phone.<p>But alas, I have a feeling that many services would not go along with this because of direct competition in the same market area. And some probably just aren&#x27;t sophisticated enough to publish an API, much less adopt a centralized &#x2F; standardized interface.<p>But I can dream.
