Darin,you're right.When I observe an RV pulling a cargo trailer,with a trailer full of jet-skies behind that,I think somehow that they'll look the other way when, an Insight or other passenger car heads out with a tail on it.
They just need to look like they won't come off and wrap themselves around a following car,causing a mishap.Just my opinion.
But if Steven Chu is serious about the U.S. ending it's addiction to foreign oil,he better give the thumbs-up to tails.
