Its easy to dismiss things as obvious when theyre done well.

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

Tesla Recall

Tesla Direct

Tesla Mobilize

Tesla Hail

Tesla Greet

Tesla Whistle

And that's just looking at synonymns of summon and hail without doing any thinking

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!

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.

That's assuming that someone would be looking at a list like that and not doing what Microsoft or other companies do where they make up their own term for features/products

Now introducing Nissan FetchDrive Plus Connect, a subfeature of CarWings ® Nissan Motor Corporation.

"Car Getter"

My favorite comment I saw on Twitter about this was just "Accio Tesla!", but I suspect the licensing fees would be a bit outrageous. :)

Consider some of the alternatives

Request car

Beg for car

Plead for car

edit:formatting

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.
