Dan Smith saw that a car share vehicle was parked at one of his duplex spots, so he built a fence around it. He said he doesn’t know who parked the car2go Mercedes May 17, but it wasn’t one of his tenants. By May 18th, he had erected the fence around the car, preventing other customers from using the car. He wants Share Now, the company that operates car2go, to pay $65 a day in storage fees, $300 for the fence and up to $500 for “harassment fees.” The company says it cannot remove the sedan because there is a fence around it. . Its policy requires customers who park in unapproved areas to pay any towing and ticketing fees. The company says it does not tolerate having its vehicles held for ransom.
