I hit an unfortunate milestone yesterday. I gave my 2010 Roadster a full charge in range mode, and the final readout was 196 "ideal miles" of range. When I bought the car several years ago, I could charge it up past 220. Even last month when I took a day trip around Lake Travis, I charged it up to 205 miles. There's a certain amount of randomness in terms of charging conditions (temperature, charge rate, etc.) and the precise number it settles on. However, yesterday was the first time I ever gave it a maximum charge and came up short of 200. Bummer. This morning it charged in standard mode to 155. I'm doing okay with it for now. It does have me pondering my future plans, though.
