Point being that google has quite a few inconsistencies in their naming (which is a thing in itself) and their not applying Google brand to Waymo at this point is any indication.

Blogger was also an acquisition (from the future founder of Twitter), and it already had a strong brand.
Whereas in 2011 there was a lot of marketing tying self-driving cars <=> Google.
There could be other reasons for the separate brand, like managing bad PR from a crash, but I would also classify that under "don't have confidence".
In contrast Tesla seems to be staking their brand on self-driving. I feel like this could backfire in the next 5-10 years, but Elon will probably make some other advance/launch to distract from that. Self-driving has already fallen behind Tesla's claims, but he can keep the media busy enough with other stories.
It's par the course for X graduates to get their own brand.
Google Video is a thing, it was Google's competitor to YouTube before Google bought YouTube. (And YouTube was already called YouTube before Google bought it.)
