Why don't people put solar panels on the roofs of their cars to capture free elcetric? That would seem to be a great thing in an electric or hybrid car, yet no one hardly does it. The only thing i can think of is the low amount of power available from solar panels.
Making a car able to survive a crash can be a bit of a catch 22. If the car is lighter, it can move with the crash or bounce out of the way instead of crushing itself, as a heavier car has to do. So it is a bit of a dilemma until carbon fiber gets cheaper.
As far as that goes, what's so wrong with using ABS for body panels? Saturn did it and the cars looked great; the panels apparently were easy to replace. GM used plastic a bit for body panels on their vans for a slight weight savings. But why did people stop using it and go for steel?
