To me, this seems like a typical "how hard can it be" startup mentality. People, especially those "fast to the market" type, tend to vastly underestimate all the corner cases of the technology, mostly tending to the happy path and outsourcing the pain to their customers. The reason they still have customers is because most of the market has the same problems and a solution that covers those corner cases is way more expensive and also way more extensive in terms of infrastructure you'd need. You would have hoped there is middle-ground there, i.e. a startup on the cheaper side with a vision for corner cases, but knowing how markets and marketing works I'm not holding my breath for that.

A big part of those corner cases is the assumption of the user being an independent responsible adult without problems. Voice control is only acceptable if you don't startle anyone with or don't have anyone talking or screaming while you are talking. Booking tickets with "one ticket per smartphone" doesn't work when you have kids. Doing basically anything that's smartphone-only requires you to have it on you, charged and for the most part with an internet connection -- great for underground parking garages. God forbid you have lost your smartphone while drunk or have been robbed -- forget driving home with the virtual car key only being in your phone, forget paying for a taxi, forget entering your home protected by a smart lock. All of this assuming the tech works perfectly and durably, which we know is not the case for most of modern tech.
