Threatening messages aimed to prevent digital piracy have the opposite effect if you're a man, a new study from the University of Portsmouth has found. According to the research, women tend to respond positively to this kind of messaging, but men typically increase their piracy behaviors by 18%.
Technically you can do so now. But you would need a metal 3D printer to build it (or make it out of plastic I guess). I remember reading something about a dude who bought a industrial 3D printer setup just so he could print out a Rolls Royce Phantom.
Printing the externals is doable today, though definitely expensive, simply from the volume of material needed, even if you can outsource or rent a big enough 3D printer (I’d probably print out of nylon powder or something similar)*.
With the exterior printed, just slap an electric motor somewhere and you’re golden (after setting up the whole rest of the car, of course)
*Actually, i’d probably print a neat looking bike frame and maybe some protection, way less material needed
