    I shared this with our local Tesla group:

    • tight loops - this puts extra stress on the conductors. Called 'work hardening', copper can become brittle, break, and the cable needs to be replaced.
    • lying on ground - in a wind, the rough surface wears the outside insulation leading to early cable failure. It is also a trip hazard for anyone walking by.
    • loop on loop - this adds weight to the cable putting stress to pull the cable from the charger. Once separated, repair is expensive and time consuming.
    If you've seen similar charger abuse or anything I've left off, please share images with this thread.

    Saw something sort of similar on our vacation trip but didn't take a picture.

    If folks had a buck for every cable untangled & unwound & unknotted, they would would be able to travel several hundred miles.

    I remember Tesla had a 'robot snake' thing they prototyped that was a metal shielded robot arm that would automatically unfurl and plug a cable into your car to charge - always thought that was nice not because it saved you plugging in, but because a lot of people have problems coiling cables and kinking them and this would have bypassed all those issues.

    As other locals have shared, malicious teenagers are also a risk to free, J1772 chargers. Hopefully they smoke tobacco.

    the gas station model worked well for a century, other than the random armed robbery or cigarette explosion.

    Tight loops reduce the current rating of the cable because the heat can accumulate: it doesn't have whole length to dissipate the heat anymore.
