The existing theories are plenty likely, but I figure I'll toss out a (probably significantly overly generous) alternative. I don't know nearly enough about the situation to really give much of an estimate of the relative likelihoods.
Imagine you deeply believe that getting self-driving cars to market ASAP is vital to saving countless lives. And imagine you strongly believe you know how to make that happen. If you aren't being able to do that in your current environment, you might feel compelled to change even if you're getting huge piles of money, and you might be willing to cut corners along the way. How much would you give up, if you were convinced it would save thousands of lives each day?
