Google is replacing Assistant with Gemini (opens in new tab)

Will I finally be able to ask my car factual questions while driving? Right now android auto's assistant experience is way worse than on my phone or watch, so I end up having to use one of those (if it's important enough, otherwise I just forget).

There used to be a time I could tap on the Google Assistant button, say "Hey Google, navigate to xxx", and it would fire up maps and navigate to xxx. Then it stopped working.

A week or two ago I tapped on what was the Google Assistant button, and Gemini popped up. I thought what the hell, said "navigate to xxx", and it worked. Yippee!

A few days ago I did same thing, Gemini popped up, accurately listed the spoken command, and did nothing. Just like the Google Assistant it replaced. I guess they noticed they weren't bug for bug compatible, and fixed it.

Even more infuriatingly, yesterday I tapped the "Power Off" button expecting to be presented with the power menu. Instead I got Gemini. Come on guys, give me a break. Why in gods name would I want Gemini when I hit the power button? You already have given yourself a dedicated button on the home screen.
