Kind of depends on the accident, doesn't it? The aerodynamic shell does provide some protection, depending on the design, and no doubt if these were mass-produced safety features could be ironed out. But if you hit a tree, you're lucky to survive regardless of what vehicle you're in. At any rate, people ride motorcycles with no shell despite serious safety disadvantages, and society has no problem with people making that choice. I have to believe that velomobiles with a shell could be made significantly safer than motorcycles. Of course, the biggest threat to velomobiles, bicycles etc. is the automobile, and if collisions with cars/trucks aren't dealt with in some reasonable fashion, all other safety concerns seem rather secondary.
