I'm split depending on the technology.
I like the idea of things like headlights that aim where you're going and heads-up displays as they make you a safer and more aware driver.
On the flip-side, I think things like radar breaking and "smart" cruise control make drivers more dependant on the technology and less attentive on what is going on around them, which to me makes them more dangerous on the roads. The technology will only go so far in saving them when they are lazy and inattentive.
I'm a little old-school and fanatic about driving, so my opinions are probably a little off from most.
