I can for 100% assure that I only nitpick because I want to understand the logical reasoning for down-voting and are scared that I am too high to understand the meaning of the phrase "It's funny you mention that". I am not a native speaker, but I know all the words, heard it in English and there exists a translation into my language and the interpretation is the same for both, so long story short ... why is it funny?
But why is that funny (haha) or funny (strange)? If they can build a self-driving car for the masses Elon Musk will be the uber-tech guy for a whole generation, and Tesla seen as one of the good guys with cool tech.
