Tim -- I am in favour of EV's -- I just don't buy in to the eutopia that is put out - I think that cutting down on fossil fuel use is a goodidea too and where it can be done without producing other problems it should be . I do Not think all the consequences of a headlong move to ev's have been even thought of fully and I just counsel caution so we don't substitute one problem with another - just like the diesel arguments -- Now latest diesels are apparrently cleaner than petrol!! who'd have predicted thatone as they made diesel the pariah.
A further thing is that one big volcano will produce more harmful greenhouse gas into the atmosphere than all the diesel cars in existence since they were invented
