It's also easy to praise things because you like the person saying them.

Why would you request, beg or plead when it is your personal car that is coming to you? Call maybe... but summon kind of rolls off the tongue better... never mind when you consider how gaming is developing and how you'd run into that particular word in pretty much any game that involves magic and 'calling' things to you.

Out of those, Direct, Mobilize, Greet, Recall and Whistle are far, far more ambiguous (with multiple meanings) than Summon. Hail is associated with taxis. If you put them all in a list it would take all of five seconds to realise that Summon is the best option.

Tesla Recall would be a terrible name. Car recalls are associated with saftey failures. Meanwhile people need to be convinced this feature is safe. There's so much more to it than using a thesaurus!
