As for the electric car it's still now ready for the mass market. Driving range on a charge has always been the downfall of the electric car. Which is why it has never sold well even though have been around for more than 100 years.

So basically electric cars are a solution to a non problem and will create new problems.
Although I do like the Tesla. I would buy one of those in I had extra money and wanted an expensive toy.
