I'm not sure how I feel about this. An ICE-prevention device like this is just one more thing that slows down supercharging at busy chargers (since you have to wait for it to recognize you, holding up the line) and that can break, leaving a stall unusable.
It's already pretty common to arrive at a supercharger and find that one or two stalls are out of service or malfunctioning because of a hardware issue, or because someone backed into them and broke them. It would be incredibly frustrating to arrive at a supercharger and discover that an ICE-prevention devices in a stall is malfunctioning and won't let you park.
I hope ICEing doesn't become such a widespread problem that solutions like this are necessary. It doesn't feel like we're anywhere near that point yet.
