Used Grok for the first time, in a Tesla, and for that purpose it actually made a lot of sense. It’s very well-integrated into the car’s systems and communication style while driving tends to be very tweet-esque. I think this is the niche they should lean into more (live assistant, e.g. Jarvis type stuff) and leave the more agentic niche to folks like Anthropic. Maybe even delegate more difficult or background tasks to those sorts of models. As a verbal interface I found it pretty pleasant.
Grok in Tesla is utterly terrible, a rushed out product with a very bad UX. As a simple example, it's the very first feature in Tesla's UI that does not come translated to the UI language set by the user but it's just available in English. Never happened before.
I am honestly a bit disappointed it couldn't do basic things, like play X on Spotify. To be fair, I accidentally activated Grok for holding the voice command button too long (which is another UX issue - i.e. 2 voice command interfaces).
I thought Grok in the car was awesome until it went off on a tangent and started praising Elon.
