<i>Do you see regulatory hurdles as more pressing than technical hurdles?</i><p>Not yet.<p>Based on what I know of Google&#x27;s efforts, I think your three-year horizon for Tesla is, well, optimistic. As many miles as Google has logged, they&#x27;re not testing at highway speeds yet -- I don&#x27;t think their driverless prototypes (as opposed to the modified Lexus SUVs) are even capable of highway speeds. Also, AFAIK, they&#x27;re only testing cars in Mountain View and Austin, which means there&#x27;s a lot of weather conditions -- and to some degree terrain -- that they haven&#x27;t had to accommodate. The most recently-given figures they&#x27;ve supplied that I can find is that they expect to be able to commercialize their technology between 2017 and 2020 -- and they&#x27;ve been working on this project since 2009. Tesla&#x27;a engineering is good, to be sure, but I would be <i>really</i> surprised if they beat Google to market in this area.<p>Now, once somebody really <i>does</i> start offering these for sale to the general public (or just to taxi&#x2F;rideshare companies or etc.), the answer to your question shifts from &quot;not yet&quot; to &quot;yep.&quot;
