Sorry I wasn't PC enough for you when I composed the title...
If govenrment agencies were serious about bike safety, (1) they would have come up with a better lighting standard than the CPSC reflector standard, which isn't legal for night riding in any of the 50 states, as far as I am aware, and (2) none of the bikes you describe would ever be for sale in a WalMart in the first place. That's a lot different than banning certain styles of bikes simply because they are different from the 'standard' bike design (whatever that is...).
