They seem to be killing this car intentionally. You can't use wall plugs to charge, and the battery rental stuff is also a mess. Apparently they were trying to sell 40k in 6 months, and only ended up selling 10k.
The world needs to stop giving in to corporate control schemes.
I don't think anyone can fault a car manufacturer for this issue. Long extension cord with too small gauge wire will cause voltage drop. It's the same for any electrical load.
Actually now that I think about it, I guess they could include dynamic power factor correction in their charging hardware and software. But it seems like a silly extra expense just to correct for someone buying a cheap extension cord. I think my 100 foot 10awg cord that I used to power the neighbor's stuff after Hurricane Sandy was under $100.
Just to clarify the conversation.
