I disagree though, DIY circuit breakers actually could burn down your house, which I think is a step up from this project. It's like a DIY kernel file system driver vs. DIY bittorrent client.

  If you put something like this in your garage and you get it wrong (despite using the right components), you can cause an electrical fire. Burning your house down seems quite possible. But I appreciate he didn't put this in his garage. However, even hooking it up to the CU is not something some random guy should be doing: https://www.speakev.com/threads/a-cautionary-tale-of-severe-electrical-fire.152651/?post_id=2872381&nested_view=1#post-2872381 https://www.speakev.com/threads/a-cautionary-tale-of-severe-... (this one was probably due to not-adequately tightening the terminals, would you even think/know as a DIY'er?)

I disagree - the actual current switching electronics are off-the-shelf relays. It's more like "didn't use a GFCI or AFCI breaker where one is required, but did try to address the same safety hazard those breakers address, in a way that wasn't as good as such a breaker, but isn't totally incompetent"

The system that controls the relay (with logic to prevent exposed high-voltage contacts while the car is unplugged, or danger if the cord is damaged or immersed in water) is just as safety-critical as the relay itself. > "didn't use a GFCI or AFCI breaker where one is required, but did try to address the same safety hazard those breakers address, in a way that wasn't as good as such a breaker Stop right there. What you describe is automatically incompetent, all by itself. Seriously, don't do this ever. There are extremely good reasons why anything but certified, unmodified hardware is illegal to install in electrical wiring. There are equally good reasons why you can't omit required safety hardware, even if you "tried" with something else. These laws are written in blood.
