Also, in my experience people who dislike AI features are often more tech-savvy in my experience. And tech-savvy people tend to know “hidden” subdomains such as “noai.” and how to change the default engine’s URL string whereas non-savvy tend to not know that.
So even if the majority would be against these AI features it might make more sense to make AI the default and noai opt-in. Because you’d lose more non-savvy people having no-AI as default than you lose tech-savvy people with having AI as default (I assume).
I drive a 10 year old Vauxhall and it definitely does not have it. I wanted to know my oil temp and had to resort to a Bluetooth obd plug paired to my phone.
