There is no doubt in my mind that sooner or later we will have electric cars, but it will only be when we find ways and means for a reasonable quick charge as well as a charge which will last for quite a few more miles than what we have now. If and when this time comes even I would be interested in buying an electric car. But until then we need to make use and do with what is available and for now this happens to be gas powered vehicles which are pretty clean in regards to emissions, compared to what it used to be.
