There will be. "Donate $1 to Waymo's autonomous safety research fund?"
And it will be offered, when Waymo's onboard AI detects you're on a date, verbally, so the date can hear.
So even if you give to charites in a meaningful way, you'll end up doing it again or look crass and be embarrassed. And as with many of these "at the till" charity collections, there is a fee given to the collector.
Who will be Google! Plus, not only do they get to track your co-riders, eg who you associate with, and where you go, and even all conversation in the car (anonymized, of course), now they get to track your charitable predilections, by offering choice.
(I know it's sarcasm and you're spot on about the charities lmao)
You own the phone. And they mostly get in trouble for lying about the things they record on phone, not for doing it.
But they own the car. And is it illegal for a cabbie to listen, and then tell their boss a stock tip, or that the Jones are buying a new house?
To add distance, they could real time listen in car, process locally, and only upload highlights as tags/text, so no recording. They could also process live, and then offer services in ride, eg "notice your hair is shaggy, Google Maps says this is a good barber!", and of course if you want that referral, as a barber, Google Maps you pay.
Google can't help itself. It is like a kleptomaniac, it knows it shouldn't, but for those voices in its head(managers), do it.. do it! You know you want to, you need to, you should!
Oh it's so shiny oh god...
And it relents, turning all pure dreams into ashes.
Waymo will be the ultimate platform to know even more about you, and to monetize it further.
