Tesla is the only electric car business that is not already in the car business.

Meaning they are not cannabalizing existing car sales with their electric car sales.

Anyway, IMO, existing electric car technology is a joke.

Energy Density (per kilogram)
Gasoline - 47.2 MEGAjoules
Lithium-ion battery - 720 kilojoules

Gasoline packs about 66 times more energy per unit of volume. Gasoline engines are much cheaper to produce. Every 4-5 years super expensive and environment poluting batteries have to be replaced in electric/hybrid vehicles.

What is the significance of energy density in your argument?
That the batterys take up more space or weight than a gas tank?
That is a minus, but I don't think it kills the technology.

The fact that the internal combustion engine is still WAY more efficient than any electric technology.
