Neighborhood Electric Vehicles (NEVs) are not safe enough for public roads. That's because they don't have to meet Federal automobile crash standards, and are very light. In any meeting between an NEV and a real car, the occupants of the NEV have a good chance of being squashed.
IIHS demonstrates this quite graphically,
here.
Anyone driving an NEV on public roads is only a little better off than riding a scooter.
