I have. The GM Impact was made available for rental through Budget at LAX. I had a 3 day rental visiting with a vendor in Long Beach and it was the 3 most nerve racking days of driving in my life.

My first driving with the Impact was to get to the vendor's office on the 405 in mid day traffic. I sat in traffic on a 93 degree day with the air conditioning running while I watched the battery level drop. While I was sitting in traffic I could only think that there would be no way to recharge the car along the way since a full charge required over 6 hours of down time and there was no place to do it along the 405. I ended up turning off the air conditioning once traffic began to move again. By the time I got to the office I had lost half of the battery capacity.

The entire time I had the car I kept my eye on the battery level and avoided the side trips I would have normally done. On the way back to LAX I was anxious about the traffic, but fortunately I had nothing to worry about.

That 100 mile rating is probably not based on a universally accepted measurement standard, so your mileage will vary. I would bet that these ratings are based on continuous operation with optimal weather conditions, no accessories running and on flat terrain.

After you have had the chance to actually run an electric car in a high traffic area in the heat and with no real chance to recharge quickly, easily or conveniently, please share your experience.

and what the heck kind of name is leaf?

I also can't get my head around the limitation of 100 miles for travel between charges. EVs don't charge up like topping off a fuel tank.
