Yes, in Germany it is illegal. AFAIK, the law states something along the lines of having "proper shoework" in order to operate the vehicle. EDIT: Whoops, no, it's actually legal [1][2] (in fact, it's perfectly legal to drive a car naked in Germany in public - though you shouldn't leave your car then, because being naked in public is not actually legal, the fine-print is that your car's interior is considered your private space), but you may get into trouble with insurance. While searching, I think I may have read that it actually is illegal in Switzerland, but don't take my word for it...
