I'm glad I'm not the only one that feels that way.. irritating...yes.
The green VW & God story reminds me of when the pastor of my church at the time (Presbyterian) literally said, on the pulpit, that she prayed to God for approval for her recent SUV purchase (or something like that). I couldn't believe it. That rivaled the time when she said, from the pulpit, that during her vacation, she was going to be replaced by a black visiting pastor, but that's OK--Black pastors can be good, too. When I asked her about that statement she said she had to set it up that way because there were some long-time founding members of the church who were a little racist and might be shocked when the Black pastor came out to preach. Wow. That insulted all of us, I think.
But getting back to Ann LaMott, I think she goes through her day trying to think of ways to weave brushing her teeth into a book. Clever, witty ways, of course.
