I liked the car story, its just that in a car I can moderate my speed to try and avoid collisions.
Without stating the obvious, how many cars do you see on the road every day, and then how many aircraft do you see when you look up?
As for Qantas with the 767s (I love 757s, and wish they were down under), I just love feeling the power of a lightly loaded one on takeoff-the power you feel! And the 767 is still currently in production, so a good aircraft.
