Crossing over

There's been a lot in the media today about the Vatican's release of a set of "10 commandments" for motorists to promote safer driving. Included in the commandments are calls for respecting speed limits, refraining from drinking before driving, and, of course, no cussing. But most interesting is a suggestion for road rage - Roman Catholics are urged to make the sign of the cross before setting out - so prevent them getting cross on the road.
