Larry should first build normal small aircraft that can do without constant manual checks before flight.&lt;p&gt;Omg, this. The amount of checks required for any sort of aircraft is ridiculous. A lot of it involves button pushing and checking status. This could be automated.&lt;p&gt;For instance, for a cessna 150:&lt;p&gt;STARTING ENGINE
Mixture – RICH
Carb heat – COLD
Prime – AS REQUIRED
Master switch -- ON
Beacon Light – ON
Throttle – OPEN 1&amp;#x2F;8”
Prop Area – CLEAR
Ignition – START
Oil Pressure – CHK
Radio – ON&amp;#x2F;SET
Transponder – ON &amp;#x2F; STBY
Wing Flaps – UP
Mixture – LEAN 1 INCH
READY TO TAXI&lt;p&gt;Most of these things could be set automatically.</text><parent_chain><item><author>Nokinside</author><text>Helicopters and small planes already exist.

Flying cars are not happening in the suburbs or anyone where lots of people live. In the meantime try to get new helicopter landing sites approved in your neighborhood. If you have to take car to your flying car hangar, just have a small plane instead. Or walk to a buss station.</text></item></parent_chain></comment><story><title>Larry Page’s startups working on flying cars</title><url>http://www.bloomberg.com/news/articles/2016-06-09/welcome-to-larry-page-s-secret-flying-car-factories</url></story>

The &amp;quot;whapwhapwhapwhap&amp;quot; of a helicopter overhead, reverberating through a home, is just as desirable as open-pipe Harley Davidson motorbikes or roaring hotrods. That is to say, it&amp;#x27;s not.&lt;p&gt;Other than a crash, I can&amp;#x27;t think of a surer way to put people off from air traffic than noise.&lt;p&gt;(edit: grammatical typo: than-&amp;gt;as)</text><parent_chain><item><author>Nokinside</author><text>Helicopters and small planes already exist.
