What are non-solid state batteries up to, in Wh/kg? Because my car with an 82 kWh battery would need about 215+ kg to reach the same charge with a solid state battery.

    About 350 it seems. There is a typical value section

    That's pretty great, for the solid state battery then. Looked it up and it seems like the battery weighs about 500 kg in my car. Very significant change down to only 215–216 kg.

    not only added range, but think of the even more fun with even better acceleration 😁

    Never had much problems with Teslas in my country. BMWs, Audis, and lately Volvos have been the reckless (speeding) drivers.

    I myself drive a Volvo, and I think that's why I've started noticing more and more Volvos, and being surprised by their frequent recklessness.

    Drivers of older BMWs and Audis have had a bad reputation for being reckless drivers in my country for at least the last 30 years. Volvo, that's a new one for me.

    Yeah, new to me as well. But having a Volvo myself, especially my electric one, I can see why these cars blast past you and it can feel like you're not really driving that fast. The electric engines are so strong and so silent that you can't tell how fast you are accelerating or cruising. You can't hear the engine(s) working hard.

    But that's what makes them bad drivers. They don't care to follow the law. The law is there for safety, not for anyone's benefit except the drivers' and passengers'. It's easy to enable cruise control, or check the speedometer every once in a while, to stay at a safe speed.

    260 Wh/kg in a good modern battery.

    But the reality of SSBs needs to be verified, there already have been scams.

    scams or definition issues. There was a bunch of stuff of what made it solid state percentage wise and if only one part needed to be it. Granted I do think it should not have liquid components if its going to be called solid state.
