Lazs,
Germany is the motoring capital of the world. The best cars in the world are built by the highest paid auto workers in the world, and AFAIC they earn every penny. They have the most sensible motorway speed limits - none.

I've never suggested a gun ban in the US. As you say, the genie is out of the bottle. Still, you guys have fewer deaths from heroin than from gunshot wounds, and you've banned heroin. And yet you claim to be the #1 drug culture in the world...
You could always do what they do in SE Asia - places like Singapore. Use a gun to commit a crime - any crime - = long jail sentence, even if the gun was not fired. Use a gun to commit a crime in which the gun is actually fired, and whether or not anyone is killed, you get a mandatory death sentence.
