I own a velomobile, which is a three-wheels recumbent tricycle with a hard shell. It is a tadpole configuration with two wheels in front and one at the rear. I had it for over six years and always have a concern regarding rear tire blowout. It never happens to me but many people owning a velomobile have scary experience with rear tire blowout. It loses lateral stability once rear tire loses traction. The Aptera has a similar configuration. I wonder your design team looks into the rear tire blowout sceneraio or not.
