“My wife’s Prius V and most other hybrids receive NO tax rebates.”
If she/you didn’t get a rebate then the manufacture got the incentives for building them.
Take away ALL the government subsidies and nobody is going to buy the glorified golf carts.
The tax credit goes to the purchaser of the car. If the car is leased, the credit goes to the company leasing the car. There is also some zero emission credits being bought in states like California. Tesla sells their excess credits to manufactures that are of compliance with the regulations.
