Most are designed for light weight.
Rider protection is often not or not high on the books.
Usual attitude :
It's better than a bike, where there's no protection at all.
Which then leads to some homebuilt designs with built-in guillotines or spears in an accident.

Second, a faired vehicle can be made more visible to other motorists by its size, color, and lighting.

This kind of vehicle is even less expected by the general motorist, leading to increased inattention blindness - i.e. not expecting the vehicle, thus not seeing it.
It's also lower as low drag is a design feature, i.e. even less visible.

Third, fairings have great potential for incorporating rider protection methods without losing the sense of the freedom of the open road. Fairings allow for crush zones front and rear. They also can provide side protection for legs, hips, and shoulders.

Sure, but how many of these designs have the kind of rider protection that would be possible ?
Finite element analysis, carrying over the load to the other side or other parts of the vehicle, designed crumple zones , ...
These things are not within reach of the hobbyist or barn manufacturer.
