Notes
This word is a combination of car and cocooning, the famous term coined in the late 70s by futurist Faith Popcorn. It's defined in the Encarta World English Dictionary (yes, this sense of the verb cocoon now appears in at least a couple of dictionaries) as "withdrawing into a state of personal privacy in order to escape stressful everyday life." Now people are escaping the stress of everyday commuting by withdrawing into a state of personal vehicular privacy.
