What would you do?

If you were you a group of Tesla owners in Minnesota, you might just take matters into your own hands.

You might, in fact, drive your cars to Iowa to offer test drives to interested buyers.

And that's exactly what Tesla owners from Minnesota did this past weekend: They drove south down Interstate 35 to Urbandale, Iowa, just outside Des Moines.

The volunteer-run test drive event was a response to the state's dealers success last month in getting the state Department of Transportation to shut down the last day of a Tesla demonstration drive.
