A trend called “ICE-ing,” involving gasoline- or diesel-engined trucks blocking Tesla charging stations, may be picking up across the U.S.

The prank involves the owners of the trucks purposefully occupying the space in front of a row of public Tesla Superchargers so that owners of the electric vehicles won’t be able to top up their cars’ batteries, reports the Daily Mail.

The most recent case of ICE-ing drawing media attention was shared by a reddit user, Leicina, who photographed a group of young men in Hickory, North Carolina rendering a Tesla station half-useless by parking their lifted trucks in it.

The men apparently yelled “F–k Tesla” and, after being kicked off the lot by an attendant from an adjacent business, tried to use their pickups to intimidate the Tesla owners nearby.

Other incidents of ICE-ing have been documented in Tennessee, Texas and other states. In one case, a Tesla owner hoping to recharge their car at the hotel they were staying at for the night was nearly left stranded by two trucks blocking the Superchargers in the parking lot.

Nine states and several U.S. cities have passed laws prohibiting gasoline- and diesel-engined vehicles from parking in front of EV charging ports, including Arizona, California, Florida, Hawaii, Illinois, Massachusetts, Oregon, Rhode Island and Washington.

“ICE-ing” has been likened by some to be an evolution of “rolling coal,” which involved owners of diesel trucks intentionally spewing excessive amounts of smoke from their vehicles’ exhausts onto nearby cars.
