A Pound coin is quite a chunk of metal. Imagine four Quarters taped together and then throw that at a moving vehicle. However I can't help to think that if you did do this in the States, you would be charged with attempted murder and threatened with 20 to life :-/

Matt,
To be honest... if you threw something like that at a moving vehicle here in the States someone would probably say to you, "Well, that was a waste of a dollar!"
Of course, where I grew up the kids loved to throw dirt clods at cars in the Summer, and snowballs in the Winter. So, go figure...
I just thought it was a pretty stiff penalty. Now just wait a couple of years... someone like me could go to jail because I don't have Health Insurance!! LOL
