There is still a huge sector of car buyers who are buying these base model economy cars for $16000, or these rust bucket used cars for $4000. Those are the people most affected by their monthly gas bill going from $100 to $200. Not the people who can afford to buy or finance a 40k asset.

Average price of a new car being 41k is the result of upmarketing. The economy class, your nissan versas, has been roughly the same price of ~16k for like 15 years. Considering inflation, that means these cars have actually gotten even cheaper relatively speaking. The people most affected by gas going up a buck are not the people who can afford a tesla, they are the people buying a nissan versa used for $6k and driving it until the wheels fall off.

Most of us live somewhere where if the price of gas goes up, the price of electricity also goes up. We don't all have a nuclear powerplant supplying our home.

If gas prices went up significantly my electricity would also go up since my grid is pretty dependent on gas. Your financial model might get a little bit complicated when you factor in that potential increase too.
