In all seriousness, I think it's a brilliant idea. I've no idea if its feasible in the real world, but I wouldn't mind a car with a fabric exoskeleton. No panel gaps, no paint chips, and (if its as clever as the concept) the ability to actually change shape? Very, very neat...
Wouldn't be surprised to see a concept hydrogen or other super-high-mileage hybrid with this sort of exoskeleton in the future...
