If they wanted to cherry pick, would they not omit that admission?

In any case, it seems plausible to me that the routes that Waymo drives are above average in human incidents, given that Waymo is probably overrepresented in high stress/traffic, inner city scenarios.

The comparison gets picked up as the headline; the admission does not. This is exploited quite often, e.g. in science reporting. I'm not saying this is what Waymo did - they don't seem to be bad actors - but absolutely, the pattern does occur.
