Ah, the 70's. Remember when there was an energy crisis in the US? People were being urged to share the ride, if you will, to cut back on the number of cars on the road, hence the development of car-pooling, to save energy.
The Ad Council had fun with that and came up with a buzzword that didn't have any more buzz than a can of flat soda. Remember "kalaka"?
I love the crooning skunk, don't you?
