Mixing saving one's life with rating for a drink in the same comment makes feel very weird. Not funny, TBH, but actually it reads like a millions of generated bad review comments on amazon, expedia etc.

It's his own life, he can be silly about it. Also the life saving isn't that literal, it avoided a crash.

When I see generated reviews they're boring, they don't have unexpected mood shifts that still fit the topic.

4.5 stars was for the ride. I didn't taste the Erewhon smoothie and can't rate it.
