I have to admit, after flying the flag for my Model S and telling the unconverted how range anxiety isn't an issue for me, I did experience some coming home last night. My trip down was 123 miles averaging about 285 Wh/m with liberal use of the go pedal. I left the race track with 143 miles of range, thinking 20 miles was plenty of cushion. I know there's a little elevation change going back up to the Blue Ridge but I didn't think that much as my house is at about 700 feet and we're close to the James River. I took it fairly easy from the start but after about 1 hour on the road my average was around 325 Wh/mi and it felt like I was constantly going uphill. At one point my projected range and remaining distance were equal. At that point I did the sailboat equivalent of pumping out my water and throwing the guns overboard, turning off my A/C and dropping my speed to just to around 60 mph. By time I got about 12-15 miles from home I had my 15 mile average down around 300 and had a 5 mile cushion. Got home with loads of electrons to spare!
