It was Edison2 that did amazingly well in the 40% offset head on crash test; mainly because of deflection. The chassis glances off of the object it hits, and this extends the time available to absorb the energy. Also, low weight helps reduce the energy level of the crash.
Combining low weight and longer time frame, is what makes a vehicle safer. Time can be provided by larger size of the crumple zone and/or deflection.
I think the Arcimoto SRK is a good design. It is weakest in the aerodynamic drag aspect. Like the Elio, a large part of the drag is the open front suspension and drive shafts, and that is why the Elio has moved to full wheel fairings. The Elio is
much longer, and that helps the aero. In the second video there is a drawing comparing the Arcimoto to the Elio, Smart, previous generation SRK, and Lit:
