Delphinus: Personally I completely disagree. Most people in a position to spend 60k on a vehicle will be businesses (or self employed) so can claim the GST back anyway. Scrapping the FBT would incentivise businesses more, who are also more likely to replace the vehicle after 3-5 years as well (adding supply to second hand market).
I don't think limiting subsities/incentives to businesses for a new EV is the way to go. Individuals would love to buy an EV but not at the price premium they currently are over an ICE equivilent. $60k is just an example, the same argument applies to all price points. Eg, the new Leaf that is being released soon has a $60k price but from specs POV it's the equivilent of a $40k-$50k car - within in the budget of a lot of individual new car buyers.
