electric cars are potentially more environmentally friendly than vanilla cars, but still pretty bad compared to a decent public transport system.<p>here&#x27;s an energy-consumption versus speed plot from MacKay&#x27;s &quot;Sustainable Energy - without the hot air&quot; book:<p><a href="http:&#x2F;&#x2F;www.withouthotair.com&#x2F;c20&#x2F;page_128.shtml" rel="nofollow">http:&#x2F;&#x2F;www.withouthotair.com&#x2F;c20&#x2F;page_128.shtml</a><p>i reckon &quot;everyone needs their own car&quot; is nonsense. sure, a nice aspirational goal for the middle-class consumer world, but increasingly irrelevant as we update our thinking to match reality<p>edit: to give a tiny personal anecdote, i live in a city with decent public transport and haven&#x27;t owned a car for over 5 years, and don&#x27;t plan on getting one any time soon. i don&#x27;t use taxis &#x2F; uber either, it isn&#x27;t necessary.
