SeekingAlpha transcript on Mobileye and Delphi partnership announcement has a statement that the two companies invest significant funds to develop self-driving car technology:
"When you think about what is needed to bring the Level 4/5 autonomy to series production, there is sensing – interpreting sensing on one hand, building an environmental model where all the moving objects and obstacles and all the path and symmetric meaning, but there is another component to it, which is being able to merge into traffic in a way that mimics human driving behavior. And there is machine intelligence to be ported into this. And there is a synergy between Delphi’s core IT in that area and Mobileye's core IT in that area and together we can bring a new class of machine intelligence into this project.
...as you can imagine just given the level of technology required and the amount of integration, on a combined basis [our investment] is hundreds of millions of dollars."
