In which country it is happening? I am sure Honda cannot extend such crypto support in all countries they operate. Government regulation plays a big role here. So while it's a good news that Honda has started accepting cryptocurrency payment it's Limited to some certain countries.
But honestly it doesn't make sense to spend cryptocurrence is like Bitcoin to purchase a liability asset like a car.
In Japan I guess according to the article, since this is very new I believe it will only be within that location until maybe other countries government decided to expand their options and embrace crypto transactions legally.
