Some things are less risky if you're competent. A lot more people think they are, than actually are, of course.
Yes, the Volt has a dinkier battery capacity than the Tesla. For one thing, for longevity, they only let you use 10.5kwh out of a nominal 16 kwh. That's why they think they can afford an 8 year/100k mile type warranty on it. But duh, you can make it bigger, use more than one, and so on. The Tesla actually gets more miles/kWh than the Volt unless you're racing, as well - the Volt is a heavy, solid car, not the latest greatest no money spared lightest car you can make, like the Tesla is.

(Yes, I'm a very serious electronic engineer {Hence the Volt}...but one who will never buy a car I can't just buy the one I just test drove. When Teslas hit the real street and I can just write a check and drive away - one of them is going to be mine - too much danger putting down that much money and hoping to get one of the "good ones" rather than the "hangover monday" cars - and the wait is excruciating).
I also find it interesting to know that Bob Lutz is an AGW denier, yet as a "car guy" really got behind this one and almost forced GM to get in the game. He's pretty impressed with Musk in this Charlie Rose interview - and so am I.

But I'm also the type of car buyer that no-way will set down a significant chunk of cash and then hope the company makes the car I ordered the right way, and without going out of business, and by the time I need it. That's Tesla's weak point right now, everything else looks peachy. Yeah, they're expensive. Find another car as nice that isn't - as Elon himself said, I realize there's no shortage of exotic-expensive cars for rich guys, that's not the point - the point is, he has to sell those first expensive ones to make enough money to stay in business so as to make the ones we normal people can afford - looks like a good plan so far.
It's just that I, like many, know that there are actual and not always subtle differences between say, cars, or guitars - play or drive 3-4 supposedly identical ones if you don't believe that - and so I don't tend to order stuff like that - I gotta touch it first, the one I'm going to get.
