I am very pleased with how well "Effie" drove on my way home yesterday on snow and ice in the Atlanta Snow Jam. Driving in L was a great help to maintain control slowing and stopping.
I wasn't able to make it all the way home on account of cars jammed up behind rear wheel drive vehicles that couldn't make it up a hill caked in ice. I spent over 2 hours going 10 miles, most of that slow moving traffic, but eventually ending in stop and go, moving one car length every few minutes. I decided to just get off the road, park in a neighborhood, and walk the last mile and a half or so home. 620 Watts per mile is what it took to drive and run the defroster to keep the windshield clear of ice. I did start to get concerned about running out of kWh.
This is a great commuter vehicle with great handling in ice and snow, but another couple of hours in stalled traffic with the defroster on would not have been good.
