So you are saying it is better to let the frustration(s) of grid lock conflict with today's rush-rush imperative so they can merge flower into full-on road rage? Never happens right? Sure. Stepping back a bit - frustration with traffic at best makes people more impatient and more aggressive on the road and that is a more potent ingredient leading to accidents than a puff or two along with some mellow music to break the cycle. Liquor (in excess anyways)- by the by- makes you less patient and tolerant- that is a well known fact.
