I think it is time to talk about so called zero emissions. One only has to refer to Christopher Plummer and Julie Andrews to know that nothing comes from nothing ( mathematicians please discuss) . I accept the reality of carbon generated in the production of mains electricity and the transmission loss inherent in getting the stuff to a convenient plug.
However I am trying to get my head around the potential for long term storage that these vehicles might offer. After all they are just large batteries sitting waiting for something to happen and with enough of them about they may provide a useful way of keeping and using intermittently generated electricity.
In retrospect perhaps our strap line of a zero emission journey should have had a question mark after it.
