invention
the other day i was driving home from the city and some asstards blew past me in heavy traffic at speeds in excess of 150 kph. that got me thinking. and the think i came up with is a clever stem valve cap for tires. when this one is activated by centrifugal forces that correspond to say 120 kph it opens the valve and lets the air out of the tires. it's perfect for spouses, judges, cops with lead feet. i'm gonna be so rich.
