At QuakeCon, John Carmack did his keynote as almost every year.
[John Carmack: co-founder of id Software and game coder of several games (Wolfenstein, Quake, Doom, current free QuakeLive and in the near future Rage) - I assume this guy is well-known (how many game coders do you know by name?) and also founder and lead engineer of Armadillo Aerospace. No matter how you look at it, this is one smart guy]
At this year's keynote, ofcourse a lot of "technobabble" (I found it very enjoyable), John starts off with id being bought by ZeniMax (Bethesda's parent company - Elder Scrolls, Fallout 3 etc), and what it means to his company, new productions, iPhone games (his pet projects it seems) and the future of gaming on several platforms (this guy knows how to talk, how to convey his thoughts clearly, there is no autocue, and it's about 2 hours before he starts answering questions).
QuakeCon 09: John Carmack Keynote
At about 119.45 (it's streaming, you can slide through to it, it will take a few seconds to load) he compares how the Tesla (I assume the roadster) compares to his former Ferrari Testarossa: at high speeds, the Ferrari was better, but at slightly lower speeds (90% of the time), he gets more grins on his face from driving the Tesla. In real day use, there is no space for a Ferrari while you can get so much more fun from a Tesla (or likewise).
"How can you drive in a car with a 200 mile range" is a non-argument to him, I agree.
Also at the moment it's sort of a eco sham (well, in his 100,000 roadster) - event though it costs 2 cents a mile, you're not going to put half a million miles on the car, so it's better to just use up your current car (according to him).
Again, starts at 119.45 - lasts to 128.10. Almost 10 mins of first hands experience, and a bit of helicopter view "visionary" on it.
