Can't say I'm surprised.

Google took a ton of heat from shareholders when they announced their self driving car project. It was widely considered to be a frivolous waste of money that would end in failure, was initiated because the engineers thought it would be fun, AND didn't have a "solid" business plan. Look at it now. Their prototypes work. They will only get better. And they opened up a potentially billion dollar market. Can you imagine a world where congestion and collisions no longer exist? Yea, that'll be fucking awesome, and due to some healthy risk taking that is completely uncharacteristic of a publicly traded company, it's in our immediate future.
