Electric vehicles are great with all the advantages that Dugimodo has listed, the big but though is the batteries which are dammed expensive to replace,will not last forever and are not environmentally friendly either in production or in eventual disposal.
The government is already talking about increasing the tax on petrol with the aim of reducing its use. It will be like the tax on tobacco products eventually rising and making it far more expensive than ordinary people are able to afford. That will get petrol powered vehicles off the road.
Nobody in power seems to have even considered how we are going to produce or to distribute all the extra electricity that we will need.
