SELF BALANCEING BIKE
2 wheeler with electronic weight balancing maybe more efficeint than 3 wheels? not sure if the cost of electricity plus weight of such system would be less range affecting than teh weight of a third wheel. need more storage space? put on a small trailer b/c most people wont need much storage space most of the time.
MODIFICATION OF CURRENT APERA DESIGN FOR LESS WIDTH (its too wide for some places especially not in america)
LENGTH FOLDING CAR
also maybe a folding mechanism could make parking cheaper and easier on both personal and on a mass scale for a local city government (cost of parking space, including less traffic and real estate issues vs normal cars over time) https://www.designboom.com/technology/casple-podadera-folding-electric-city-car/ it can be done by using rear brakes to stop the car and front motors to push the car into the folded position. the frontal wheels can also turn inward to fold in for compact at low speeds where weight distribution stability is not as important as being compact in crowded places and parking https://www.triggo.city/.
this can be another product for any car for the growing expensive parking space market https://www.aptera.us/forum/main/comment/60303cc5b65b71001706471a
USE OF COMPRESSABLE STORAGE RATHER THAN HEAVIER SOLID STRUCTURES :
also a retractable body shell can make the car compact when extra space is uneeded and especially when extra space is often not used, such can be something like a bag on rear or roof of teh car, or a retracting solid chasis structure: https://www.youtube.com/watch?v=3mEkE7TMNZw. https://www.aptera.us/forum/aptera-design-discussion/cargo-holder-gizmo
SMALL 4 WHEELS
also how about having passenger and driver back to back, so the vertical center of weight of occupants are at the center of the car not only for a more occupant centered weigt distrubutin for dhandling experience but also for a more aerodynamics freidnly design, and it may end up a lighter car, plus the passenger can streach out legs into trunk area when no need for to store much in it, and can lay legs over items in trunk, can access items in trunk, can simply retact legs if trunk is in use, plus crash saftey is better with backward facing seats if crash accidnet happens from the front of car and same for driver at front if crash is from behind:https://www.consumerreports.org/car-seats/why-kids-should-stay-longer-in-rear-facing-car-seats/
BACK TO BACK SEATIGN POSITION:
2 dimensional side visual perspective:
the square is teh trunk psace/ extra legroom, the triangle is a place to put electronics/batter (preferably teh heavier parts) or a storage space, the other red lines that teh triangle sits between are seats. any interior empty space can also be taken advantage of as storage space even its wall space rather than floor space by a net holding objects by a rope tightener (something like this thing used in hoodie clothing to tighten teh hoodie: https://www.amazon.com/Inovat-Plastic-Toggle-Spring-Single/dp/B01JWJ911S/ref=asc_df_B01JWJ911S/?tag=hyprod-20&linkCode=df0&hvadid=193122865658&hvpos=&hvnetw=g&hvrand=13556882858479421763&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9007795&hvtargid=pla-305509099122&psc=1) 2 wheels at front 1 wheel at rear may still be practical, especially if front wheels are behind the pedals , and car will probably be shorter front end to rear end b/c much trunk space maybe not needed if there is a trailer for when need for more space happens (it wont happen often especially given most people most of the time drive alone and without using much of trunk space. plus if passenger needs more legspace he can adjust his seat backward, round mechanical teeth gears on a rail on which teh seat slides on forces incremental movement rather than sudden movement to prevent startling the driver by moving his eat to quickly. then teh driver would have less leg space, but driver passenger can switch leg space by asking each other for more depending on their needs, and conflict is resolved by intuitively switching back and forth on a need basis for long drives (which also dont happen often). having less necessary legspace means shorter car.
if the only three wheels are in contact at a given time, the forth wheel wont take away legal exemptions the car can benefit from by having less than 4 wheels, for ex in this pic teh side wheels can only touch the ground if the car leans on it, or 2 wheels at front and one at back there can be small wheels next to teh theird rear wheel like kid bike training wheels, or the lean can be on three wheels and teh front and rear wheels interchangeably touch teh ground depending on weight distribution. the distance from the ground that any wheels has is to be small so that there isnt too much body roll for people with sensitivity to motion sickness etchttps://www.aptera.us/forum/main/comment/5ff3d90a937ccd003b4aa10f
NISSAN DELTAWING GT:
https://www.youtube.com/watch?v=qe3nAFMhwnc how about something like this, where 1 seat in the middle, 2 behind that driver seat with some legs room next to driver, like gordon murrays t.27
also it may pay off in terms of aerreodynamics maybe even weight savings at some level, given teh ability to carry 3 people/more storage space, than vs teh cost to benefit ratio of a 4 seater. if the seating position was like this: at where the red X is marked minimalize teh space between rear seats, have them face in a outward angle towards where the side mirrors would be if there were normal side mirrors, there will be considerable space behind the center driver where heavy parts of drivetrain can sit ex. battery, diesel generator etc. there is actually decent leg room for the rear passengers as shown at the red circle, they wouldnt be able to spread legs apart fully but will have space to stretch out legs and move them enough to prevent cramps on long drives.
this one combines the passenger facing backward behind the passenger and the concept above for a theoretical happy medium in capability vs efficiency costs: the red is the body dimensions, teh black is where wheel axles may be (teh rear shows that t may pay off for aerodynamics to have teh axles more near teh rear end or teh axles near the weight of teh passenger and whatever is stored next to him (ex battery or whatever), to allow for quicker ability to put down torque if reader axles is driven by powertrain)
a 2 seater version seater of this can be a happy medium between putting passenger behind the driver and passenger next to driver:
also, given how often people travel alone, a single seater may be worth it given a single seater can also replace public transportation for "last mile" transportation in crowded areas and in l where public transportation isnt being used in teh locality. this is especially viable when considering teh single seater car can be used on teh highway and can be brought home for anytime use, unlike public transportation that often has availability limits, scooters are often abused and are probably not even "environmentally friendly" either https://www.youtube.com/watch?v=0NY6mHADWCk.
PROJECTORS/E EINK DISPLAY TO ELIMINATE BLINDSPOT
durability of wheel coverings:
also make wheel coverings easily removable if people want to off road, where people usually dont drive very fast for aerodynamics to help anyway ex. camping, or at a local park etc. the wheel coverings shouldn't have to be a worry on bad roads like how you would have to worry in some sports cars, the worry of having to think about potholes is a big part of why people want higher ground clearance "SUV"s instead of cheaper sedans. this is important for making aptera more mass adapted, and a passenger trailer system could eliminate worry about not having a 4 seater car b/c family or whatever: https://www.aptera.us/forum/aptera-design-discussion/increasing-average-efficiencies-by-rental-of-usually-uneeded-things the passenger trailer can have a back to back seating arrangemment: https://www.aptera.us/forum/aptera-design-discussion/more-efficiency-and-midengine-sports-car-like-handling-feel-with-alternative-seating-position-for-4-seater the passenger trailers should have to back seating position
