Liquid cancer? C'mon, that's a bit extreme.
Getting down to the point, can you imagine the political fallout from crushing the value of a gas car? It's a truck sized political landmine, and no party is willing to touch that thing with a hundred foot stick.
Gas still has significant advantages that electric has yet to match. Worst gas has 53x the specific energy of the best Li-ion, and even with a hundred % efficient induction motor and a 10% efficient motor (try closer to 30% realistically), gas is still a much more energy dense fuel.
Still, gas has a ton going for it. It's quicker to "charge" by an order of magnitude; it's easy to carry an auxiliary supply to double or triple range. Cold weather and reliability are excellent (hundreds of thousands of miles with a minimum of maintenance). There are no concerns about cell wearout (batteries will last for 5 years, maybe). Virtually everywhere on the planet, there's someone in any population center who knows how to work with gas cars.
The network for gas is highly developed and highly entrenched. No one is giving up trillions in value without a fight. In all honesty, I expect to see gasoline powered vehicles on the road for the next 100 years, barring an unprecedented revolution.
