Exchange on the Toyota Prius

Did Toyota's Prius get Japanese government money?
That question has stirred up some talk.
It started with a Business Week report, which quotes a former Toyota executive as saying that it did.
That comment was just one line at the end of a long article.
But a person I got to know through blogging pointed it out.
So naturally I had to at least try and ask Toyota.
That produced this article.
Reaction was instantaneous:
One
Two
Three
Four
Five
Just some above and there's a lot more, including the response from Toyota U.S. on its official blog, and a response from Business Week.
And another.
For me, it was this reaction that got me thinking I should get busy and find out, producing this story.
Also on Prius online.
The account with updates on this blog, and this one.
Topping it all, perhaps, in potential controversy is this.
