Although the article did not elaborate much about the countries in which this will be accepted since Honda is a world brand. But it will however spread to more countries keying into the idea. The btc community wants mainstream adoption and I believe this and many more like this will pave way for that so-needed adoption.
You did not closely inspect the news source and also the replies on your own thread.
The article cites in which country it is supported, and there is a reply in this thread that addresses it.
You better update it on OP since most users also did not dig deeper about the linked sources and this thread replies, so they still asking about in which country the cryptocurrency payment option is available. Lastly, this kind of news is surely spread the awareness of the current state bitcoin adoption, but we must remind that this does not depict the whole picture of Honda directly favour and accept cryptocurrency payments.
