This might seem silly but I've noticed my elbow and even knees seem to land on uncomfortable hard spots in every car. I like to drive long distances. You have to get comfortable, settle in on these drives. I'm 6'2" but I think everyone, if you let your legs lean over to the side, your knee caps wind up leaning on something hard. It's uncomfortable. Same with the elbows on the door side of almost every car. It would be great if there were more consideration for long term driving comfort positions.
I see a convergance in the design of tadpole recumbent bicycles and the Aptera. Recumbent bicycles are going electric and there tires are getting larger. If you aplly the same desgin priciples of the Aptera to a one seater. You may have a nich market for one passenger highway traveling ultra light, ultra eficient and ultra safe. If that takes off some of the cost it may be the best entry level electric. A single in wheel tire motor in the back may cut costs with a weight reduction. Recumbant bicycles have had serveral fatalities and your pasanger cell would be a great step forward in a one seater. You may even have a market with motor bike alternatives. I have collected these youtube videos regarding this convergance. https://www.youtube.com/playlist?list=PLPRDK5fXWg8Ru_PsZDEeYkltF6MJp2QLs
