    Darwin awards happen all the time not sure how thats Teslas issue. My buddy has model W, he sets it to charge into the 90s not to 100% as its better for the battery pack. Its like a child to him

    How complex is charging on these vehicles? Isn't it just a "plug it in and leave it be" deal with them? Granted there are different ways to charge (normal in-home 110v, enhanced 220v in-home, Superchargers at various locations), but I thought the car does all the work.

    At my new job I need to charge forklifts whenever they are not in use. The system is simple and takes less than 30 seconds to plug/unplug and is very safe/moron resistant.

    Itís only that simple for the user because the engineers designed in a very complex control system that does all the work.

    That's what I'm saying. I don't understand the belief that users are going to burn down their house or electrocute themselves with these systems. Sure, accidents CAN happen. But overall they will be super low count.

    Itís because there is so little margin for error. One uncaught bug and it can be catastrophic. Itís an extraordinary amount of energy stored in a fairly new medium. Storing gasoline and moving it from a tank to a car doesnít require a complicated set of algorithms and safeguards. Those that are designed into the system are well-tested and have been around for a long time.

    Correct. Every new thing that comes out for cars, my mechanic brother has to take a new class on it. When electric vehicles first came out, the first thing he was told was not to touch Spot A and Spot B at the same time, otherwise he's literally dead. In the long run, this is really really new technology being applied for the masses, and there is a lot that can go wrong if not designed correctly.

    Moving gasoline from a tank to a car does involve safeguards, NEC has a whole chapter on Gasoline equipment, NFPA 30 has multiple sections on gasoline safety. DOT has a special license for drivers of gas tankers.

    Yes, and I specifically mentioned that gas has those. Iím just saying they were developed over decades. We havenít had electric cars in a majority of households for 50 years yet.

    The NEC has plenty of these guidelines. I get that. But now weíre dealing with extremely high amperage being put into peopleís homes and actively used daily in an entirely new medium. Iím not saying this is like handing people a flask of hydrofluoric acid. But this isnít as mundane as we would like to think.
