Re: No second hand market
"I can't wait for my Tesla Model S to be delivered. It is due next month. No more buying petrol/diesel."
So you can afford a Tesla and many can't. The affordability is, of course, improved by subsidy from the rest of us including those who can't afford a subsidy. You'll find that the subsidies get phased out over the next few years; as the numbers of EVs increase the shortfall on taxation from VED and fuel duties will see to that.
