While I can understand the furor, any acts of violence or ICE shaming will get the public perception of EVs nowhere. Keying? deflating tires? Bar of soap? REALLY?
As one member put it, 5 minutes relief, life time regret. Anyone considering such action should stop reading/contributing to the anti-EV and anti-Tesla threads because of obvious hypocrisy (looking for smiley with gloriole...)
In fact, it could be a Volt, a BMW ActiveE, or a LEAF that blocks a supercharger slot. Never attribute to malice that which is adequately explained by stupidity.
IMO it is OK to inform the driver that his/her behavior is causing trouble to any Tesla drivers, and that s/he could get towed and fined in states with according laws (CA, FL, ...?). Contact your representative to push for legislation and/or enforcement of it. But never be the offender yourself.
