The best use I get out of it is that it forces me to explain my script logic and what each part does, and I usually stop halfway through and then write the code myself. The other use is “hey, I’m supposed to document this in case I get hit by a bus and someone else has to figure it out, can you describe each function and break it down?”
The tax credits are just a money grab for the manufacturers and dealers. If you do the math, a 68k loan with a 6-7% interest rate and the $7500 tax credit has the same total cost as no tax credit and a 0.99% rate. That’s why they always offer “manufacturer incentives” with $0 due at signing or those 0-2% loans, but almost never both.
It really depends on if you have good credit or not to make the tax credit a good deal.
