The subsidies are a remarkably inefficient way to increase uptake.

If government wants to invest in EVs, there are two sensible courses of action.  First, encourage private industry to invest in supporting infrastructure.  We need quick charge stations along our major highways, since range anxiety is stopping many people from considering EVs.  Second, invest in post secondary research projects to improve batteries.

If we must subsidize purchases, let’s do it by waiving the GST or offering interest free loans.  Direct payment to owners is unfair to those that cannot profit from the advantages of owning an EV.  Sort the range problems through robust infrastructure and improved batteries, and the market will take care of itself.  Subsidize well-heeled owners and EVs will remain a niche product.
