While there has been some discussion around whether Silicon Valley companies like Alphabet, Tesla, and Uber would be able to upend traditional automakers in the race to develop self-driving cars, it seems increasingly likely that the future will be driven by partnerships. Building cars is a difficult, complicated process, which car companies like Ford, GM, and Fiat-Chrysler have down to a science. Although Tesla has arguably become the first successful new US car company in decades, it still doesn't produce vehicles at a scale anywhere near that of Detroit automakers. Waymo recently partnered with Fiat-Chrysler to develop cars for its service, and Mercedes producer Daimler is doing the same for Uber. GM also purchased a self-driving car startup, called Cruise Automation, for $1 billion in 2016, a move not unlike Ford's investment today.
