Too true! But the other assault on older cars is the change of fuel mixture. For example the new petrol being produced has more sulphur in it which I believe can damage older petrol engines and fuel systems. As you say once they've got rid of petrol/diesel electric cars will not only be taxed to death but the cost to us both in electricity price increases as you stated, but also the increase in taxes due to the I creased need to build more power stations.
