Waymo didn’t “say” this. Or at least the article this article references doesn’t claim they did.
It’s a now third-hand paraphrase from an SF bike advocate who says he heard it from some unnamed representative of Waymo.
If someone has something more direct, happy to read it, since this seems to be clickbait napalm at the moment.
Thank you! I've seen this all over the place the last few days. It's clickbait from a cycling group and very few people have actually bothered to read it.
