As the Chevy SXSW Road Trip Challenge rolls into its final day, Team Detroit continues to dominate the scoring, opening up a nearly two-to-one lead over its nearest rival, Team South Florida.

It’s looking like Team Detroit might be unbeatable as the teams approach their destination, Austin, Texas. But from the start, this competition has been less about winning than about having fun and reaching as many people as possible.

To that end, all of the eight teams are winning. Just ask TV star Alysa Milano, who tweeted the following message in support of Team New York: “Help #NYChaos win the #ChevySXSW and keep NY pride alive: http://is.gd/aesvr (via @ iamkhayyam ).”

If that isn’t a measure of success, we don’t know what is.

Be sure to check out all of the action on Chevy’s SXSW Road Trip Challenge Posterous page, where all the teams are posting pictures and videos and of their adventures along the way to the SXSW Conference.
