This strikes me as an interesting approach that could maybe be generalized by a company like Uber.<p>We know some of the biggest problems with self-driving cars are:<p><pre><code>  - Needing extremely precise, up to date maps
  - Inclement weather &#x2F; conditions
</code></pre>
Which suggests to me that if you chose a particular city, mapped it out extensively, and then only allowed these cars on the road during good weather conditions...you could deploy these things much, much more rapidly<p>And of course since consumers wouldn&#x27;t buy a car that they can&#x27;t use much of the time or take outside the city limits, the natural use-case of this is as an on-demand taxi service, like Uber or Lyft.
