@spendius,
The thing about electric based cars, that Caroline is so blatantly ignorent about, is the inefficientcy. It was once before explained to her, that the recharge time is very long, and therefore impractical if you use it frequently or more people share it. The batteries must be replaced just as any car battery and therefore increases the cost over time, in collisions it's unknown to me how the battery acid will behave, if it's safely harnessed or it will spray all over the place.
She even mentioned the solar cell cars, which has NO practical value for this discussion, which only show's her low sense of rationallity. Are they crash safe? No! Can they carry a heavy load? No! Can they take more than 1 passenger? No! Do they have to have special driving conditions? Yes, roads must be closed for their exclusive travel, and too heavily reliant on sunny weather ...etc..etc.
Dear Caroline, I say this again, you are overly emotional, therefore makes very irrational statements. You should make deeper thoughts about this matter, and realize what you say is rash, unthoughtful and doesn't make sense.
