And you missed the point @Mike3425 : we have a huge culture about EVs here and yet we never plug into any socket for charging without asking. We don't need to warn anyone because we ask first.
It would apply to anything plugged in without permission, yes. Because here we don't take things that are not ours to take.
As for the theft it's like shoplifting. If you steal for less than NOK 5000,- you get fined. If your theft is above NOK 5000,- you could face probational prison (that's prison outside a prison facility). We just had a profiled politician fined for stealing sunglasses in an airport shop...
Legislation attached.
