I think the best way to roll out self-driving cars would be to build up a base product (like Google has done), and then open source at least a large portion of the software. Run a campaign that anyone reporting a critical bug gets their name on the underside of the hood in every first generation car that Lexus/Honda/Toyota and Google collaborate on. Then, run an ad campaign based on X thousands of programmers reviewing code totaling X thousand days of effort. Easily the safest strategy, and it gives an easy response to any competitor: how many programmers have reviewed THEIR software?
