They say the best thing about it is that the only thing that comes out the exhaust is water vapour. But isn’t water vapour more of a greenhouse gas than carbon dioxide? Doesn’t it trap more heat? What would potentially be the effects of the whole planet running cars that release water vapour into the atmosphere?

They run on electricity, and that means they don’t belch out loads of fumes into the atmosphere.

But that electricity has to be generated in a power station before it can be used in the car, and nine times out of ten, you can be sure that it was generated from fossil fuels.

So surely, electric cars are still responsible for polluting the planet.

That’s just about the dumbest, most poorly thought through answer I’ve ever read.
