writes "We've seen Tesla run into regulatory issues in Texas. And North Carolina. This time, it's Ohio, where car dealers are playing an entertainingly brazen brand of hardball. The Ohio Dealers Association is backing an anti-Tesla amendment to Ohio Senate Bill 137--which turns out to be an unrelated, uncontroversial proposal about drivers moving left when they see emergency vehicles (The bill is headed for adoption.) The sudden and subtle amendment would ban Tesla from selling its electric cars directly to customers, who place their orders online with the company after learning about the Model S in company-owned stores. A hearing on the amendment was suddenly scheduled for today; Tesla is fighting back by outlining the economic benefits to Ohio--after taking some legislators for a ride in the Model S (a Tesla tactic that has worked before)."
