Silly (but genuine) question – what's to stop the likes of Tesla increasing the price of their vehicles by whatever amount the subsidy provides?
Eg. Government says "here's a $15,000 cheque with which to buy an EV", Tesla just puts up their prices by $15k per model?
(Assuming they are happy/content with current sales levels which I imagine they are due to the Model 3 production delays/restraints).
They want sales, happy for a Govt to stump up some R+D
Forget Tesla they are overpriced and not a great build quality. Buy from a car manufacturer
