Gas cars are great until you realize you have to replace the gas. Then you'll realize the cost of owning a gas car.

Once people realize they're literally burning the expensive gas they put in their vehicle, the game is over.

Also, gas is a limited resource which after you burn never ever comes back, so it is expected to get more expensive, while all the rare earth metals in batteries can be recycled into new batteries because when you use the battery, you aren't actually burning it away into nothing. You can even recharge it.
