...and the victim's name? The electric car.

Looks interesting and depressing.

From the site

Every gallon of gasoline burned in a gas engine auto adds an average 19 lbs of CO2 to the atmosphere

Really? 1 gallon = 19lbs. ?
Isn't that a bit much?

They are probably adding in production, transport, distribution, etc

(just on a guess)

Not really. The mixture ratio of oxygen to gasoline is ~2.5 to 1

1 US gallon = 3.78 liters = 6.1 lbs of gasoline

Now multiply by 3.5 = 21.5 lbs

The excess is probably H2O

Alternatively you can note that the mass composition of gasoline is ~85% carbon

0.85 * 6.1 lbs * (44/12) = 19.02 lbs

44/12 is to take into account the fact that the gasoline contributes 12 g (1 mole of carbon) to every 44 g (1 mole of CO2) put out by the reaction. The rest comes from atmospheric oxygen.
