I drive my Leaf from Altadena to the Cathouse in Rosamond and back (After charging) every Sunday. I use the I210W to the (2) Angeles Crest Highway to the Angeles Forest highway to the 14 N. It is 69 miles one way and it takes about 1.5 hours, although I allow 1.75. By using the mountain road I cut the distance by about 16 miles, and I can use slower speeds on the steep hills. I typically try not to use more than 20kw's of power to climb hills, which keeps my speed around 34 in most areas of uphill grade - would not advise that on the 14N. I keep my speed around 45 on the down hills, gaining lots of charge. From Rosamond to LaCanada I can arrive with 4 bars of charge remaining if I try, typically it is a full three. On the way to the AV, it is more elevation gain, so I typically get there with 2 bars or in the recent 20 degree weather up there I see the first LBW less than a mile from my destination, which has a 240 outlet I can use but is not for public use. With 30 miles of freeway in the AV, I tend to drive about 5 mph under the speed limit (70 for about 15 miles). If traffic is light I will slow to 55 in areas to conserve charge, speeding up when needed.
I got caught one Sunday a few weeks ago when the snow closed the Angeles Forest Hwy after I drove up in the AM. Not seeing the road closed sign I started up and went 5 miles before seeing the barricades at Aliso Cyn, so 10 miles added to a cold, rainy, and hailing evening with my wife in the car. Returned to the Sierra Hwy and began using it, but opted to get back on the 14 after a few stop signs. Traffic was slower(45ish) that night due to the hail so the regen got me to the Golden Valley exit with 4 bars of charge - so we opted to eat at the Habit, and grab an hour of L2 at the Kohl's there. DET/GO meter flucuated between saying we could make it home and could not make it - I would have opted to go slower and try, but I was hungry anyway so listened to the wife (Always a good plan). Back on the freeway I kicked it up to 65 again for about 10 miles, then dropped the speed as much as traffic allowed. Total distance that night was 97, with about 45 miles at 60+ mph. Hit LBW as I left the freeway in Altadena but made it home with one bar. Defroster and heater were used, but sparingly.
