He will then do just what he would have do if the ICE car breaks down. I think your scenario and the ICE breakdown have similarly likelyhood.
True, also gas pumps also don't work if the power is out. So if you needed gas you're also stuck!

Right. Happened to my son traveling to SoCal at the bottom of the grapevine two weeks ago when it was closed due to snow.

I'm going to throw this out as I think it will be ineteresting to see who has or is going to have the longest LEAF commute. I' m suppose to get my LEAF in March. My commute is going to be 125 miles round trip with 120 volt charging at work (10 hours). 30 miles or so at 50 to 55 mph up and down hills, a 20 mile section at 65 mph and then 12.5 miles at 45 to 55 mph.
Also I'm at about 1500 feet elevation and work at about 30 feet elevation (Foothills to the Central Valley).

All I can say Bassman is you got balls. Not trying to rain on your parade but if you can do it my hats off to ya.

Three things pushed me over the edge into actually buying this car (beside being a geeky Electrical Engineer). One was the fact that it's the first eCar on the market with the practical capability to meet my needs (I, like gudy, was a Volt man when the Volt pitch was electric which of course ended up not being), two, rebates (12.5k$ here in CA), and three, the fact that I could meet all my needs using the charge equipment in my garage. In my mind the practicality of "gassing up" outside my garage was just not realistic enough for me due to the time required to stuff the energy in this beast (admirable as it may be and chemical reactions being what they are). As the out-in-the-wild charge stations become available, it will offer additional exploratory "opportunities" but did not affect my purchase plan. With your place of work offering charging it changes the calculations to the extent that you can rely consistently on it. Keep in mind my power charge measurements indicate you can get 4.5 mi/hr of charge at 120v (1.44 kw) and 12 mi/hr of charge at 240v (3.77kw). Of course a L3 charge station fairly close to your place of business (+/- 15-20 miles?) would significantly change the analysis in your favor.

So when I'm showing off my LEAF the question I get asked the most is, "So how far will it take you on a charge?" My response is always the same. I say, "Well I look at it more like this. Who is the ideal purchaser of this vehicle (ignoring purchase economics)?"

1) You own a gasoline vehicle that you are going to keep, and
2) you travel less than 75 miles per day.

Can this 75 be stretched? Sure it can. It's just my pitch on what I see as the optimal owner of this vehicle. If you want to travel more, then you get in to all the marginal tactics to make sure you don't get stranded (no climate control, go real easy ALLLLL the time - not to mean I don't ALWAYS run in eco mode as I always do - always "looking over your shoulder" regarding range.... heck... who needs it).

I know there are a lot of eCar lovers out there like me but there is a point where it doesn't fit a particular situation. In the future there will be vehicles that have a greater range. With your daily commute you might be one of those that would be better suited to wait until that time (though I completely understand your interests.... after all, we're all junkies on this stuff or we wouldn't be here on this forum). Now that's not to say you should not purchase this car, but maybe, not purchase this car for purposes of your daily commute. Also, I'm not saying you can't pull it off but rather I don't see it as an ideal fit.

Also I'm at about 1500 feet elevation and work at about 30 feet elevation.
As mentioned the hills will kill you. A Leaf fully loaded might be 1750 kg. You might go 1000 meters -- that would ordinarily be a lot elevation gain but you're looking at 500 meters even if you didn't have hills between home and work. And of course gravity will be gravity.

The math says that you'll use 4.75 kWh hill climbing each way. You'll get some of that back through regen but perhaps only 25%. In that case you're looking at using over 7 kWh just for hill climbing, which may be more than half what you'll get charging at work.

That means that sans hill climbing losses you'll need to go 120 miles on about 28 kWh, or almost 4.3 miles per kWh. That's borderline doable but throw in cold weather and bad weather and a couple of years of battery degradation and you may find yourself short of charge with some frequency.

A 240v charger at work would help a lot.
This app tells you the altitude of points on a map. So for instance I can see the altitude of my home, of my work, and of the valley in between. Early on at least I might keep a log of trips to give me a better idea of influences on range. I already see that I should note temperature and whether I use climate control. But also for some of my recurring routes, I might record elevation loss and gain.

Of course what I'd really like is for the car's computer to look at origin and destination and topography inbetween, and initial state of charge, and use that to refine its range estimates. But since the car can't even seem to manage yet to shut off charging remotely, I don't think I'll hold my breath for more esoteric features.
