I have driven a plug-in for quite a while; 2013 Chevrolet Volt, 2017 Chevrolet Bolt EV, and 2018 Chevrolet Volt.
I relish the quiet drive experience.
I hope Aptera makes good use of sound dampening materials on the interior of the vehicle. It makes a huge difference – even given a highly efficient aerodynamic design.
Look forward to your progress reports, design details, and hopefully parking an Aptera in my garage!
reason for sportiness:
although quiet is ideal in life in general, its not good for people to get too bored driving so much so they try to entertain their selves by playing on their phones as younger people do nowadays. yes theres is music, podcasts, radio etc but people still are often into their phones. making driving more interesting keeps drivers attention, which is what sports cars happen to do when used what they were made for, but there is also hypermiling without partial self driving stuff. see under "SPEEDOMETER", and the stuff about pedal around there.

to make driving more entertaining, encourage hypermiling and enhance perceived quickness of car https://www.youtube.com/watch?v=_V_HjDMU6js the feeling of quickness is not directly correlated with actual quickness. car should like extension feel more like a glove than a remote control for a robotic arm
enhancing the feeling of speed can make a driver who isnt worried about getting somewhere faster feel hes going to faster over the speed limit, encouraging him to drive slower, increasing experienced range, and driver would only go faster if they want to get somewhere faster thus actually check the speedometer often to drive as fast as legally possible. a more interactive driving experience also incentivizes driver to be more attentive to driving rather than getting bored and distracted by phone texting or something.

monotonous sound is often not recognized b/c its "white noise", and non constant rate of bumps being felt on road sometimes knocks the daydreaming out of people, which is good for bringing attention back to the road.
unique sound?:
low aerodynamic friction around occupants make wind noise very low compared to other cars with same level of noise dampening, especially if it was tandem 2 seater https://www.aptera.us/forum/main/comment/607c74a6da92970132747547 .with less wind noise and less noise dampening, driver can hear hear wind noise of other cars relative to their location on road, so u can know when a car, even a electric car, is coming near you by wind noise alone. hearing more of the outside environment is something one arguably wants for same reason why someone would want to walk in around the neighborhood or at a park (feeling more of the environment is why people like the roof down in "convertible" cars) . of course nobody wants things to be "too loud", at least so people dont have to raise their voice talking in car. hopefully you can get more fresh air in the car than other cars, that would increase the driving interactivity.
