Most of the price is in the copper inside. Walk around with an insulated bolt cutter, and you can make a lot of money. Alibaba will sell you a device to get the insulation off the wire. Plenty of scrappers bring copper into the scrap yards already.
I wouldn't do it, but it is easy to see how a dishonest person could make it work.
The cable can be cut with $30 Bolt Cutters, and sold to the scrappers for its weight in copper. Multiply by the number of cars charging that night on one street. Faster, cleaner and tons more profitable than cutting catalyst converters from under the cars.
It also has up to 32 amps of current running through it. Better get those industrial cutters with proper insulation =)
BTW, are all scrappers completely unethical? People steal the weirdest shit for the value of the metal and they always seem to find some scrapyard that'll take it and pay for it.
