> ? Do they have hailing? I thought you would have to use an app. I´d call this an example of language evolution comparable to 'calling someone' which used to involve either raising your voice so the person could hear you or walking towards wherever that person is but now involved pulling out a communication device which bridges the gap between caller and callee. The same goes for 'hailing a cab' which used to involve standing on the side of the road, hand raised and possible shouting 'taxi' upon which a horse-drawn or self-propelled vehicle with driver pulls up to drive you somewhere in return for payment but now involves pulling out a communications device which bridges the gap between customer and 'driver'.
