In the abstract, one could believe that an electric car would be uncomplicated. But that doesn&#x27;t seem to be true.<p>For example a few days ago we discussed the BMW i3. Electric means simple? No. Someone in that discussion posted a link to a 40 min video of the i3 production line. I had no idea of how much effort was involved. <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11532982" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11532982</a><p>Yes, electric cars are inherently simpler than internal combustion vehicles. But they&#x27;re still quite sophisticated, with quite a lot that can break or become obsolete.<p>There&#x27;s a whole like more than the battery that needs a &quot;technical revolution&quot;. People have been embracing recent developments such as automatic crash braking and Apple CarPlay. It would be difficult to retrofit all the sensors needed for automatic braking and lane change warnings.
