Living on the Oregon Coast, we frequently get horizontal rain. Some sort of enclosure will be a must if I am going to be able to drive my FUV as much as I would like. My preferred version would be one front door on one side and one rear door on the opposite side. (You don't need four doors on a two passenger vehicle)
It might be really cool if the front door was a suicide door while the rear door would be conventional. Both mounted in the center (on opposite sides). That way they could share the same mirrored hinging mechanism perhaps simplifying things. You could make each door larger for easier access since you wouldn't need to fit two doors on the same side.
It would look really cool from above when both doors are opened. Also, since it might be difficult to incorporate an opening window on the two doors, having a ridged panel opposite each door might make it easier to have an opening section.
My 2 cents
