POWER SHORTAGE: Test-Driving the Nissan Leaf. “Since I needed all the juice I could get to make it to Burlingame I decided to forgo the pre-heating and let the Leaf charge to the very last second. Fortunately this morning was a hair warmer than the day previous being a brisk 40 degrees. Unfortunately the temperatures and humidity conspired to fog the windscreen. Without sufficient power to make it to work and use the defogger, I chose to defog the old-fashioned way: windows open.”
