Usually it's a gasoline car blocking access to a charging station. The word for this is - that the station is ICE'd. ICE being Internal Combustion Engine.
But what's the term we use when a Tesla Model S is blocking access to a charging station?
This group of Volt drivers decided upon the word - "Musked"
What one supposes is that this Model S driver saw "Oh, here's an electric car parking spot - what a nice perk" and parked in the spot even though they weren't planning to charge their car.
The problem with this is these are not a parking spots, these are charging spots. Those spaces are supposed to be reserved for the act of charging an electric car.
Another problem is that public electric car charging infrastructure is positioned as a "parking lot" model of usage, rather than the "filling station" model. That's because of the charging time required for Level 2 charging - several hours for a full recharge. The filling station model (in-and-out in 5-10 minutes) doesn't work when it takes several hours to refuel the car.
In any case - Model S, parked in an EV charging space, but not plugged in - Musked is the word. Tell all your friends.
That leaves the question of the word for a Leaf, or Volt, or Plug-in Prius, parked in an EV charging space and not plugged in. This does happen, it's not just gasoline car or Model S drivers that are at fault. Not all the electric vehicle owners have learned the etiquette. Tell all your friends about the etiquette, as well.
