In a tweet, BYD promised this is not an April Fool's joke. We're apt to believe them, as in January, the company launched the world's largest electric double decker bus. We haven't covered BYD much since it was helping Uber test electric vehicles, but the company has been busy producing electric buses. It has manufactured more than 50,000 in the past nine years. If you can't make it to Colombia to see this latest creation, you can catch the K12A in action in the tweet below.
