It also makes it easier for passengers to access. I am afraid it might be just a concept feature at the moment I would like to see it get carried through to the production stages.I was shocked to see it have suicide doors but after seeing these pictures, it makes sense. If you have all that space and covered area in the rear 1/4 panel area, might as well use it to help out another area of the car.
Not having a B pillar in the way will help with this car being more versatile
