That's a fair point, but of course speeding is against the law, and rightly so ;)

It makes sense to take responsibility for your own folly to an extent, but when something is obviously dangerous and addictive I don't think it's an entirely bad idea to make that thing illegal to deter people from doing it. I still keep hoping the bloody smoking ban will force me to quit properly at some point...

And on points of etiquette, you should never laugh at someone's opening. Terribly bad form.
