I’m actually shocked at the inefficiency of the electric powertrain tbh. An F-150 Lightning gets twice the distance per wh, a Model Y is quadruple. I’m not entirely sure if it’s just simply the size, but the lightning has a comparable gvwr. Just seems weird to me
As OP mentioned, it’s not relevant since he retired, but the seat becomes vacant for a period, meaning one fewer member votes, and results may be affected. There’s generally some mechanism for filling the vacant seat, which can vary on timing (and state law). Generally a replacement can be appointed by the state governor, special elections are held if there is still a substantial term remaining, or the position is held by the appointee if an election is already imminent.
