First, let me say that I feel bad for the guy who died and his family and friends and any employees he had who may be affected by his demise. I also have to say that I'm glad no one else died who did not choose to be part of this experiment.
Also, I have to say that this whole thing makes me uncomfortable as hell. There is almost no way to predict how another human being is going to react on the highway, and that concerns me enough, but the thought of any number of computer issues from hardware to software glitches of any kind causing a 3000 pound vehicle to do something completely random is just downright scary. I get why some people want this to be ready and they want to be on the cutting edge of technology and all that. This guy looked pretty pleased with himself in that picture and I get it. However, if the technology isn't ready, you sure as hell can't rush it. I'm not sure if I'll ever feel comfortable with it, but I'm sure it will probably be the norm eventually if we are here long enough to see it.
