This is only an idea but logically it would solve the issue. What we need is a 20ft Supercharging extension cord. So whenever someone tries to ICE the Supercharger spots you would pull directly behind them (blocking them in) then pull out the 20 ft extension cord and plug your car into the Supercharger as usual. You essentially will be blocking them from leaving. I would be willing to bet they won't be too happy to have to wait an hour or two until your done charging. After the word gets around that Tesla owners are carrying these with them then I'm sure the ICE-ing will taper off.
Let me know what you think.
