And if you, as a legislator, think bringing money and jobs into your state doesn't matter, you have another thing coming:

You'll find endless concern from every state about how to attract businesses and jobs to their state. It's not a coincidence that Hyundai opens a manufacturing plant in Alabama instead of someplace cheaper or more recognizable.

The problem with New Jersey doing this vs. Alabama is that the mechanism for Alabama to get Hyundai is pretty direct and pretty clear. Offer incentives to Hyundai, get a plant and a couple hundred jobs (plus the indirect halo effect on the economy outside of the plant).
For New Jersey it just looks like they're protecting shady car dealers by generating an artificial monopoly. The optics on it are terrible, it looks corrupt and petty, and the public rationale "it helps the consumer" is clearly false, but the practice is pretty much the same.
There's absolutely nothing that prevents Tesla from setting up a franchised dealer network in New Jersey, selling their cars cheap to the dealers and then having the dealers keep a cut while generating jobs in the state. It's "spreading the wealth around" from CA to NJ a bit. The only thing that prevents Tesla from doing this is that Tesla wants to maximize the profit share they see from the car sales.
The thing is, because Tesla has been very public about it, they know there is room in that large 25% profit margin per vehicle (Honda makes about 15% per hybrid) to "share a little".
