also the space in red can be location for bags with the same hoodie tightener concept(would need higher quality metal and maybe larger version of plastic hoodie tightener) that can be expanded around the car for storage in case of occasional use, and they can be compressed away into teh trunk:
also a teardrop trailer can be helpful for storage, and the bags can be structured for aerodynamics when trailer is in use. this allows for more storage capability when needed, sp when not needed, teh weight penalty nessesary for facilitating more storage is not always being carried when everyday driving, thus better driving range. the trailer could also be for passengers, and more:https://www.aptera.us/forum/aptera-design-discussion/increasing-average-efficiencies-by-rental-of-usually-uneeded-things
air pressure braking
about the bags, they could also be used as a way to store compressed air that comes from a pump that is pumped by wheels air pistons countering wheels forward movement to slow it thus slowing the car as brakes. the inflation of the bags would mess up efficiency which is a good thing b/c aerodynamic friction helps slow the car especially at higher speed and for lightweight car. this decreases or even may replace need for friction brakes at times, decreasing/eliminating running costs of eroding brake pads. bags can be deflated naturally when air pressure is enough to push against a spring which opens up a pressure exhaust valve, increasing back pressure that the air piston/rotary brakes provide. more aggressive anti aerodynamic stuff can be activated by the same air pressure like aileron wing type stuff.
the air could be let back out through the same pistons/rotary air pressure device from wheel to move the wheel as a 2nd level of regenerative braking, except it doesn't transfer electricity like electrical regenerative braking thus increasing battery life although it maybe required to regenerate electricity by using air pressure to push gearing in motor.
a clothlike plastic tarp like layer can separate stored stuff from compressed air bags, and the stuff carried is held in place pressed against teh car via net and "hoodie tightener" like device, to prevent stored objects from moving around while driving.
also notice teh compressed air braking has less regenrative potential when more things are stored there, thus friction brakes will probably still be needed but brakes wont be used as often thus will have much longer life so less costs of replacing eroded brake pads.
a foldable solid structure roof storage box to have better aerodynamic structure when carrying on roof (although weight cost of this vs a bag held down by netting, might not pay off from aerodynamic improvement)
how about using nets that can be losened or tightened with a hoodie toggle https://www.amazon.com/Inovat-Plastic-Toggle-Spring-Single/dp/B088T5M83B this can be used to replace plastic sturctures of storage places built into the door, allowing for decreaseing width of car.

I think if you need to go through all this you have the wrong vehicle.
