~20% weight reduction for a total vehicle weight isn't small change. Plus batteries will continue to improve as well. Do you just get off on being negative?

    Yeah, I'm not sure how they concluded in their edit that 400kg is not a lot to shed.

    The gains compound a bit too, 20 percent less weight equals proportionally less battery capacity required to shift the now-lighter vehicle from point A to point B.

    So then you can cut the size of the battery while maintaining the same range, and that's where you start to get significant overall weight and cost savings.
